See about possibly switching classes.
Lots of behaviors are overlooked before school, those little things that you find cute are not so cute at school.
It’s okay, making contact with the school counselor should be your first place to start, setting a meeting with child’s teachers and administrators, & some behavioral therapy you can be part of in the meantime.
Don’t be discouraged, it’s easier to correct bad behavior the right way when a child is still learning basics.
If you feel they’re being nit picky, see if you can “shadow” him at school. So you can directly see what he’s doing and correct the behavior. Idk since covid is going, if they’d allow that. But doesn’t hurt to ask. 
He’s a freaking 5 year old for crying out loud 
My two little guys were both really good in preschool and then had trouble in Kindergarten… My youngest ended up having to be transferred to a behavioral school and he’s amazing here now… maybe talking to the teachers about what should be done and what they suggest for it and go from there
Switch him classes and see how that goes. I thought about doing the same. My daughters never been in school and this is her first time… on her 2nd day she didn’t get recess because she was talking to another student! But that student got her recess. 
I’ve noticed a few kids in my daughters class are related to the teacher in some way. I will not stand for her treating my child differently. I mean it was the 2nd day of school! They said if they take their recess parents will be called and a letter will be send home. Nothing was ever sent home or even called! I only found out cause my daughter was crying her eyes out over it!
Is it a “bad behavior” trend going on in kindergarten right now? Across many mom groups, I have seen so many kindergarten parents getting these notes daily and 5 year olds getting sent home for behavior. At my kids school they have all of kindergarten being taught by substitute teachers. I just removed mine. After a 5 year old called her teacher a libtard Democrat (it was funny, but not funny because she obviously didn’t know what she was saying but repeating what she hears) for coloring the wrong answer. 
it’s too much for these little kids man. 
I recommend switching classes because it could literally just be the teacher. I’m speaking from experience my kindergarten teacher would complain about every little thing I did even when I wasn’t doing anything at all. She just genuinely did not like me from day one & I mean to the point where I still remember almost every bad interaction with her which was almost all of them. Hopefully that’s not the case and everything works out for y’all but it’s better to be safe then sorry.
Kindy has a lot more sitting still, paying attention, and academic work than preschool. It’s a big adjustment for any kid. Teach him about consent and the school’s rules for touching but also make sure he’s getting self regulation breaks and exercise. One of those fidgety chairs helps a lot, to burn energy and help focus. Hang in there, this will pass.
THIS is why I pulled my son out of Kindergarten after 2 wks. Every day they were calling me telling me he’s doing something wrong! They are sooo strict and rigid with these little kids its crazy! We are now homeschooling and he’s doing great!
I had the SAME issue with my son when he started kinder…. He had been in a daycare center since he was 6 months old and always had good behavior, not to scare you but it turns out my sons teacher was right, there was something wrong… he was in DKA and I had no idea. He had type 1 diabetes. Get him checked out just to be safe 
Pull him out and homeschool. He will turn out to be a much better human
Switch the class or even school.
Talk to his doctor first and make sure nothing is going on with him personally… if he checks out to be good… request he is put in a different class. It may not even be a situation as to where the teacher doesn’t like him or he like her… different teachers have different styles of authority and teaching and he may do better with a different style
To be honest some places are just not the right fit for some kids. My son was the same I had never ever seen him act out in a physical way ever and it was never a issue in his daycare his first year of school within 2 days he was being labeled a bully. I pulled him from the school in his first 2 weeks and he started at a super small school with only about 100 kids max he’s now about to graduate at 11 he’s a school leader and I have literally never ever have had 1 incident of him being a bully in 6 years. Follow your instincts take a chance to randomly turn up during the day jusy to see what he’s doing. Don’t let him be labeled and pushed out poor boy there’s more to it.
I suggest looking at the environment things may have changed at home or day care also just show up out of the blue and watch from a far or spy through the fence at kindy to see whats going on
Them teachers also have picks and chooses too
Face the issues and address them? Kids are entitled because parents are so occupied making excuses. If he’s not doing these things, I’d understand frustration but if they act out, behavior needs addressed.
It may not be him it may be the teacher or another child’s influence. I agree with Taby Davilla.
This is very common it will get worse through first grade there is a big learning curve right there but will even out for you hang in there mom
Can you go and sit in the classroom and view this
Just talk to him. My middle son did the same in kindergarden, we talked and he has gotten a lot better. At that age he can understand you.
How old is he? Imho it’s better to wait until boys are 6 to send them to kindergarten. With boys the issue is typically social maturity. My oldest son was 6 with a May birthday when he started his true kindergarten year. He did two years of kindergarten and it was purely for social development. He was a leader not a follower through school because of this. He went in to the military and had the same experience there. It’s worth considering.
We had this exact situation. My son was always “the good kid” then suddenly it was like he couldn’t do anything right. The teacher literally told me he was the worst kid she had ever taught in her 20 some years of teaching. I was SHOCKED… and in tears. I had no idea what was going on. Turns out it was a teacher problem. She was bullying him in school. Ridiculous things like she said the class was out of pencils and asks if parents could donate any more. I sent it 2 packs (it happened to be on Valentine’s Day) she made him stand in front of the class and sharpen them while everyone else had a Pizza party because she was mad I didn’t sharpen them before I sent them in. She didn’t even allow him to bring home his valentines because she said he was on punishment so since he didn’t get the party he didn’t get the valentines. I pulled him from the school the same week.
So I just had an issue last year where in preschool my son was having behavioral issues that started out as small things and they didn’t share until they were so out of control that it took a while to address them and correct them. At that point I asked them to share with me what was going on so I could address them sooner, not necessarily punishment or anything but help the teacher understand the best way to get him to relax or deescalate the situation. There is good chance he may have been doing some of this stuff before but the school you were in figured out how to work with him and just never told you. Your son is new to this teacher so they may be looking for some advice on what works for him and to keep you apprised of the situation. I always ask too what happened right before the behavior so I can try to see the trigger. For mine it’s reactive aggression where he feels backed into a corner and everytime they would talk to him instead of letting him calm down first it would escalate.
My son had the exact same issues coming into daycare! You have to be on the same page as the teacher and really work on enforcing hands off at home. If you’re spanking him or yelling at him nothing will change, you have to ask yourself what are you doing that’s not helping him learn this? If you’re doing everything you think is right then maybe seek some behavioural therapy. It has amazing results for kids especially if problems are caught early!
My concern is the teacher. Does she like him? Is he being treated ok?
She may not be telling the truth.
I say this because when I was in 2nd grad back in the day I was abused by my female teacher.
That very teacher chose one child every year that she abused. Back in the 70s it wasn’t like it is now.
I was finally rescued by my first grad teacher when I went running down the hall into her arms.
She called my parents.
The 2nd grade teacher did not lose her job.
Because why? It was the 70s. That is no excuse. But I really don’t know why.
Today she she would have been fired.
So sit your son down and talk to him. Let him know he is safe to tell you anything.
And if there is any other classes his age with different teachers, get him transferred out of her class and see how he does.
Have him tested for ADHD
My son was having the same issue when he started. Luckily the teachers are super nice and supportive and are trying to get him settled into his new school routine. We do little pep talks before school and a special sticker after school. He enjoys having the teacher tell me about his good day at the end of the day. They’re young, it’ll take some time to settle in. Hope this helps a little! Good luck momma
sounds like a normal child to me
Children aren’t designed to be crammed into a classroom indoors full of children for the length of a full time work day.
I’d go to the school and ask them what is triggering him to do this because he has NEVER been like it and refuses to even kiss family
This whole thread is indicative of a problem we have in society, not holding boys accountable. It’s always someone else’s fault it appears. No, what you should be doing is teaching your son about consent and body autonomy and that his behaviour isn’t acceptable. If he’s acting out you have to get to the bottom of why he’s doing so not teach him to ignore that to keep others happy. His behaviour needs to be addressed because little girls shouldn’t be subjected to being kissed by boys. I think that lesson should be taught to all boys at this age as part of the curriculum.
have a sit down one on one with his teacher,maybe sit in on a class iff you can…if it seems out of character for your child…I never took anothers word for when my kids started in school…you can even sometimes request to observe when your child don’t know you are there…this day and age I know it’s hard…but always believe in your child first and foremost…ask him how the day went EVERYDAY and be involved…JMO 
<3
Same thing happened when my son went to prek I was surprised he was getting put on yellow. And some of the stories just didn’t make sense. He is in 2nd grade now never gets in trouble and teaches always praise him. I feel like it was the teacher that had the problem.
Is he being challenged enough in his learning it seems like he may be getting bored and this is the way he expresses himself in relation to this, perhaps sit down with him and ask what he enjoys at school and what he doesn’t enjoy, might also be an idea to sit with the teacher one on one and see their point of view on this at the end of the day your child should be the main priority and if this is out of character then it’s time to figure why this could be happening and figure out what can be done to support him, regards an early years educator 
Kids have a difficulty expressing themselves with words because they don’t have the words. So they communicate through their behaviors. This seems like he may be acting out due to something stressful. Has something happened? It could be the starting at a new school with new kids. Have you talked to him about it? Asked him if he liked kindergarten? This may be helpful in figuring out his behavior
Can I just say -
This year has been so tough… There’s been so much going on in the world that is unusual and scary.
Our kids are dealing with alot, from what they see around them to what they pick up of overhear and not forgetting they usually can sense how we are feeling.
Whatever you decide to do just remember that and be kind to yourself, your doing an amazing job and so is your son. 
We are all living in a pandemic and our littlest humans may just struggle at times to process this on top of everything else.
Personally I would try and seek support from people close to him, family , gp ect to see if this behavior is happening in other circumstances and then go from there…
My son seeks connection with others through touch. So kissing, touching and getting code to others was actually him being nervous and seeking a bond with someone. He has recently been diagnosed with possible ASD.
TaLk to the teacher and make sure she’s challenging him. If he’s ahead of the class-he will get bored and possibly act out. Maybe advance him to first grade
Talk with your son…ask what he did at school and if he tells you about his behaviors it’s an opportunity for explaining proper behavior, boundaries, asking permission, actions that are acceptable in public and school. If he doesn’t mention any if it tell him Mr or MS Teacher said you were kissing so and so (or whatever issue you want to start with)…how did that go? And start the discussion not scolding but talking about what is ok and not ok for school.
Troublemakers always had the most friends when I was in school, it was the smart kids who followed the rules who were friend poor!
I used to help in a school, teachers have no time for children that don’t sit quietly and do as told, and label those naughty and constantly pick on them…I used to take those children and give them my help later they turned out to have autism. The point is the teachers have no time for those that don’t fit the line. Could you speak to the head of the school, ask for him to move class. He young he doesn’t need the attitude from the teacher. I hope it all works out when our kids have problems it makes us feel sick…could you think of home school? Take him out for a while? Ask someone independent to observe him?
Kindergarten is not required. Maybe he should be kept home another year with parents teaching h the basics. Something to consider after checking things suggested in the other comments.
He didn’t have strep throat lately? I saw a big change in my son’s behavior after a bout with Strep. He was so sweet and did what he should. Then it was throwing garbage cans running from everyone, hiding under desk… at home was worse tearing up his room, crying, angry at everything.
Eventually it goes away and he is back to his sweet self.
He may be bored and not stimulated enough with the learning aspect of things so it’s leading him to be disruptive it happened to my eldest and once they realised and pushed her a bit more she calmed down
theres two sides to the story. sit and discuss with your son. you wont believe such bad behavior goes on in school even at such young age. or he may be mimicking to fit in.
My son had bad outbursts at school when he started. He also did years of nursery school and never had an issue. With each transition in kindergarten he would become angry and knock things down, one time he knocked everything off the teachers desk . It was completely out of character for him. Turns out he was feeling nervous in a big environment where they were changing rooms for library, gym and music. It’s very overwhelming to a little one. We had many conversations about counting to ten to try to relax when he had to transition from one task to another. Eventually he worked his way out of it for the year. But each September he will spike with behavioral problems for the first month until he gets back into the swing of things. Good luck.
I’m a retired preschool teacher. Make sure your child has not been inappropriately touched. It happens and a child that young sometimes acts out because they dont know how to talk about it. It’s a horrible thought but it’s something that should be considered!
Sounds like the attention is the motivation. Unfortunately, the kids reacting is probably what’s maintaining that behavior which you can’t realistically avoid, really.
I am troubled by notes back and forth. I think a face to face with the teacher is a first step.
Or could he of had the same issues in preschool and they were deemed developmentaly appropriate and not addressed. Or hes copying other kids behavior… I work in preschool. Kids dont have emotional control until 6.
I would get use a letter from preschool as an example of his previous behavior and bring it to the school comparing the letters you are receiving now then I would ask for his class to be changed maybe he’s acting out because of the teacher and her/his level of patience.
Just sit down and talk with him about it. Start having evening time with him every day about what happens today use it as a fun talking and teaching session. When you talk with him explain to him about what he does and how it affect him, others and life. Make it a fun session, a mommy and son afternoon time. Give him advice and tell him how he should keep it. Give rewards. Be creative with it. I have a son and when he was that young we had a WHAT DID YOU TODAY SESSION, it was our time, we shared our day and what happened(I didn’t tell all my work day stuff lol). Etch out some personal time for your children. My son liked microphones so we act as if we were newscasters. It was our one on one time. I used these times to talk about character, to listen, to teach. And today he is a great 36 yrs old handsome chocolate young man that take time to lend an ear and help others. GOD bless you.
Have him arrested and thrown in jail and permanently labeled as a sex offender. No seriously - it’s bad behavior just like any bad behavior and should be dealt with in the same way. You need to help him figure out why he is acting out and ways to control his impulses. Does his school offer any kind of pull out counseling services? Sounds like he might benefit from something like this especially if it’s in a small group setting of his peers.
Possibly bullying, or something bothering him and this is his reaction? I am def not an expert but this is what came to mind first thing. I hope you find the answers 
Go to school. Observe him in class from an off area. Kissing other students…. do you kiss him at home? Is it affectionate… ever forced for any reason? He could be using it as a way to bond or aggravate. Who is he kissing? When? He’s a baby. Everybody needs to take a breath. He needs to be taught social boundaries… . It is normal for children of that age to hold hands, huh, kiss, link arms etc…. but if his classmates are complaining that IS an issue that requires some investigation. Go to school. Watch your boy.
Is he copying off someone, try and help in nursery one morning per week to see if you can find what’s going on.
Teach your child consent!
You step over the disrespect. It’s your home, your family is not teaching appropriate boundaries.
Needs a father figure that doesn’t work at Victoria’s Secret
Sounds like he is being bullied and it’s his way of retaliating.
"Use your words, not your hands’. Google lists of words to use…i bet pinterest has lists…or teacher resources…post on fridge…talk about the different words…make lighthearted but serious examples…
Why is it that every second kid is being diagnosed as having g a behaviour disorder?
I agree with keeping him home one more year.
Talk to the school counselor or take him to a child psychologist.
Maybe he needs more attention at home I don’t know
My son is going through the same thing
He is growing up, changing.
Troublemakers have fun lives, let it ride…
Go sit in the classroom for a few days if you’re allowed to and see what ACTUALLY is behind the behavioral change.
Change of classroom??
Maybe see if he has adhd …
Someone has shown him this behaviour if he’s not doing it round you. I’d speak with him and ask him who and the teachers ask them when it was first seen and who with
I was kissing boys during nap time in first grade but I have no idea if that was normal or not, the boy was kissing back
The problem cud be your new boyfriend
I agree with what someone said earlier. This sounds like what my grandson and daughter went through. I begged my daughter to talk his pediatrician. He was tested and the diagnosis was ADHD. They put him on medication and the change was amazing. My daughter had never wanted him labeled and medicated, but now she surely sees a difference. There are also lots of things that can be used in the classroom that could help him. My grandson is in 3rd grade now and still uses them. One of them is a stretched band around the bottom of his chair so he can move his legs around . It is an outlet for him. Just remember that he may not be able to control it. That could leave him very frustrated
He could be Neurodivergent (ADHD, autism etc) I am severely ADHD and I have autism. Which means I have a lack of impluse control, and have a hard time trying to figure out how act in most social situations. And before anyone says “well that doesn’t sound like my ____ who was diagnosed with autism” everyone has different presentations. I am super creative, have a wild imagination, and was super chatty. There are a bunch if other factors but his behavior could be something to talk to his doctor about.
Teachers today make a Mountain out of a mole Hill everything must be by the book .No if’s or but’s .A lot Kindergarden Teachers have NO kids of their own .Please don’t take her remarks as a personal problem for your child .Sit down and explain to your child that Kindergarden is different to Daycare and the teachers have there own rules and its better to just follow them to keep the Teacher happy .But very soon he will be in SCHOOL where their will be so much fun .Time goes so quick .
My son had trouble with kindergarten bc he was already reading & knew alphabet, colors, words etc. it was frigging boring for him! He had to be challenged on a daily basis. Here is a kid probably the same with a teacher who probably has 25 or more other students. She needs him to go along with the program, sit be quiet, don’t cause a ruckus, in other words blend in. He is standing out & teacher can’t handle it. I volunteered in my son’s kindergarten class & my job was to babysit one student who was a real “problem”. He did have concerns in that he could not interact with others, was destructive & violent. As a nurse I could see he really did have issues but as a parent I could see that he really needed help the school was not providing. Bc he did need 1:1 watching he was transferred to a “special” program. That emphasized to me how inadequate our schools are for supporting our teachers. Without parental help that teacher or other kids could have been hurt.
Sounds like the teacher may be out of her depth and not keeping him challenged. If he is smart the material may not be stimulating enough so he acts out of boredom.
Kinder teachers are the absolute WORSt… especially with boys. If your son doesn’t sit still/shut up and never be annoying they have a problem… there is no patience… I honestly feel most of them hate kids. Have him transferred to a meeting class. It’s her problem not his. There are some hateful adults in this world now
Maybe the issue isn’t with him … Maybe its his teacher … I would request a meeting with her to see what is actually going on because her nit picking is going to harm his self esteem …
In my experience with my daughter’s schooling, more then likely it’s the teacher and their approach on certain things. My daughter had a teacher that if your child wasn’t a “cookie cutter” student and didn’t fit her mold, she would kind of toss your child to the side and write home about how misbehaved they were. My daughter has ADHD and ODD and she knows how to play adults and boy did she play that teacher and give her a run for her money 
Have you asked HIM whats up? like tell him y’all need to chat but reassure him he’s not in trouble at the moment, y’all just need to come up with a way to keep him out of trouble together. Maybe talk over a bowl of ice cream…the more he knows he’s not in trouble durning y’all’s chat the more likely he is to tell you what’s actually going on
First…When he was in preschool…was it full days? Was it through the actual school system? Or was it more of a daycare?
Those to me are HUGE factors in why your child possibly wasn’t having issues until now.
It’s easy enough to be well behaved for 2-3 hours. Harder to be well behaved for 7. And while many daycares call themselves preschools (at least in my area) and have a “curriculum” it’s not really comparable to an actual school system.
It’s important to remember also that what is or isn’t appropriate is also based heavily on age.
Second…is he acting up more at a specific time of day? Or All day? If it’s a specific time look into what’s going on around that time frame. Maybe he’s hungry or thirsty.
Third…address the issues with your child. Start by asking them questions. Do they remember doing xyz? What were they doing right before? What were they feeling? What did they do after? Do they know why they did xyz? This may give you some additional clues about what is going on.
I’ve seen this on both sides…with the same child.
My oldest has severe ADHD and mild ODD. His teacher the first time he went to kindergarten didn’t believe that ADHD was a real thing. She was pretty much bullying him but also giving in to his ODD. The thing was…she didn’t really complain. She swore up and down everything was fine.
But at the same turn, he’s had great teachers who’ve struggled with his behavior. And reached out to me because as a mom, they wanted me to be aware.
I remember his meds were off a couple years ago. His bus driver had so many issues. He had to write my son up…and on the slip he just wrote please help. He wasn’t angry with my son or anything. He hated writing him up. But it was safety issues so he truly had no choice.
I had this happen to my son. It was so out of character for him. When I went in to speak with the teacher, nothing she said sounded like my son. I asked her what does he look like? She said he has light hair and is taller. I replied, well my son has dark hair and is on the smaller side, I think you have the wrong kid. I brought out a picture. She says oh my gosh this kid is the sweetest and kindest kid in my class. I have been mixing up the names of the kids. Yep, teacher had the wrong kid. I her defense she did have 3 Joeys in her class.
It’s kindergarten that’s how little boys are have a talk with him about it
Ok first of all that teacher sounds absolutely ridiculous calling your 5 year old child "disrespectful " over this. I would call her and say look I understand that this is an issue but my son obviously is having a hard time adjusting. But don’t you ever call him out as being disrespectful just because he’s being a little handsy. I would actually flip over that. Disrespectful? Thats unbelievable to me. A 5 year old thats acting like this is not being disrespectful on purpose and it shouldn’t even be a thing. Hes having trouble not being disrespectful.
See if you can observe, child teacher relationships are crucial, if the teacher dislikes him he will act out. Get involved on side of your child, get to the bottom of it. Most importantly, ask your kid what is going on.
I would ask to observe the class without him knowing your there. Ask your kiddo what’s going on at school. His age they don’t understand I guess you could say respect for other people’s bodies. I wonder if he’s also looking for attention, whether it be negative or positive. My 7yo is like that.
When my oldest was in 2nd grade I kept hearing about behavior issues. We had just moved to a new state and getting use to a new school, so I passed it off for a bit. But it seemed to be almost a daily thing so I eventually talked to their teacher. The issues he was having were due to her asking to many questions, so he labeled it as not being quiet. Thank goodness my kid wasn’t deterred by it because some kids many have had their curiosity forever lessened by such an experience. The following year, and every year since, my child has been labeled as great with an amazing mind for learning. Humans don’t always get along with each other and I found out that all teachers don’t care for children willing to challenge the status quo. I’m not going to blame the teacher for all these issues your child is having but sometimes it is just as simple as this particular teacher and a student do not click and it makes for a really stressful year for all involved, especially the child.
I experienced the same with my youngest I changed him schools
Haven’t heard a negative thing since.
Make a appointment and talk to the teacher
Ask to overlook the class one day without sons knowledge.
