Mine are the same way my 6 year old doesn’t get a choice , I worry about rashes or even a uti if she’s not wiping correctly,her teeth isn’t an option my oldest was the same she’s 8 now and loves showers etc I just explain to my 6 year old how hygiene effects her health …i think simple things like proper hygiene isn’t rewarded its expected maybe that’s a mean way of looking at it but everything doesn’t need a reward ,I don’t raise my voice or take anything away if she moans about it sometimes they gotta do stuff that they don’t want to for their health, I get her a bath bomb every weekend for a Sunday pampering which she likes just what I do I remember my oldest fighting not to its nonsense hygiene isn’t optional its my responsibility to take care of them and maintain their hygiene.You can approach it on a fun way like a sugar bug chart where they put a sticker for everyday they brush the bugs away and get a treat I did that for her when she was 4 but at 6 she knows better cavities hurt even with baby teeth .
We started early with our kids. Hygiene is just a part of their schedule. Has made it easier to add bits like deodorant and face wash now that my son is getting older and needing these things. I do always remind each child what they need to do and make sure they have washed/brushed or whatever.
Girl my 6 year old needs a little push its normal lol
I think it’s just kids my kid in 15 and has a rule that they shower every Monday & wed during school time yet if on school holidays they don’t want too shower then that’s up too them unless I tell them they smell then they have too get one b4 4 that day or lose there electricals for the rest of the day
Tell her you need her to clean the bathtub. Fill it with water and baby soap and give her a rag and tell her she has to get in to clean it. Tell her you will oversee the task. It should work. If not have her watch Big Daddy with Adam Sandler. Lol hope it helps.
Structure boundaries and routine. She is only 6 years old 
unless she has other problems make it routine and assist her
Who’s the mom and who’s the kid. Last I knew moms were the boss about something like this
I literally asked my kids if they want to be the smelly kid in class? They said no, so I said well then get
Your hiney in that bath then lol
They still don’t love it, but they also don’t throw fits
No excuses no amount of tantrums, be the mum. Run the bath, toys, bubbles etc your having a bath that’s it. 
hugs whatever you do enjoy this time kids are so cute…and your teaching love youself to keep the temple clean. when the conseguences are small let her have them. could you use peer pressue with the clean one
Good luck! I had to drag my son into the bathroom and sit in there to make sure he was using soap. I think some kids are just stubborn.
Goodness I have to tell my 16/18 yr olds to get showered and brush their teeth hair etc 
Show her videos of what happens if the bacteria in her mouth is not address. You can always give it a try
Bath paint! My daughter is almost one and she loves bath time because she gets to paint and play with her toys 
but remember your daughter is 6, not 16. You really can’t expect her to just do everything herself lol
Lead and repetition
Doing it over and over at the same time every day
It sets a pattern
Since she is only 6, bathe her, brush her teeth, and help her get dressed. And style her hair. Wait until she is a little older to give those responsibilities to her.
Let her share a bath with your 8 year old. Instead of making her take separate baths. That way she’ll learn and have fun bathing with her sis
You can only teach by example and by involving your child while you do certain things.
Bathing isn’t a choice at any age. It’s a necessity. I Upon waking up and going to bed. Children need structure. Come home homework,play Freshen up for dinner more homework head for the shower/brush teeth Sleep/brush teeth/shower eat breakfast/ brush teeth…never ending cycle period…
Neurodiverse people often face these struggles. People sit here and talk shit, but don’t even understand the full scale of what might be going on for this child.
Sticker chart with a privilege or prize when filled?
Some things are just not a choice. Try setting a specific time every night, like after dinner, with fun bath toys and when bath time is done then have dessert and a movie.
Slap the shit out of them into the bathroom.
And by the way it begins at home.
You have to have the ritual. Started when young in family life.
You are the parent, therefore you are the boss.
My mother used to tell it was time to take a bath, time to brush my teeth at that age. Same with my kids End of story. 
Show her photos of young people with missing teeth due to poor oral hygiene.
Her classmates will eventually relentlessly tease her into bathing and tooth brushing, I know this because I was the kid with the snarly unkempt hair in grade school. Make it a routine and a chart with stickers, and a little reward every month for daily compliance.
Sticker chart with tasks morning and nighttime routine put sticker on chart for each item she does
I still shower my 7 yr old. We stopped doing baths unless they are sick, having a day, etc. But, she can’t wash her own hair and would never take a shower if I didn’t tell her bath time and walk her to the shower. My 11 yr old son showers himself, but definitely has to be told. And then reminded. And then told again. And then reminded to use soap! 
They alternate every night so I don’t have to worry about 2 showers plus my own every day.
Fill up the tub put your child in it. And sit in the bathroom with her until she’s done.
Let her smell. She’ll learn that no one wants to be near her
She might feel out of control of aspects of her life and uses being dirty as a sort of shield against it.
A 6 year old should be doing what she is told. Full stop!!!
Unpopular opinion: HYGIENE IS NOT OPTIONAL. Get your ass in the bath or I’ll put you in the hose.
She’s… 6, how about parent her and tell her when it’s time to brush her teeth, help her when it’s time to bath etc. My youngest daughter is 8, and I remind her EVERY bath to wash certain areas. Who the fuck expects a 6 yr old to just get up and brush their teeth? LOL really??
Talk to her as an adult. Why they’re important, the consequences (losing teeth, cavities, skin rashes, social issues) and tell her she needs to do it. No rewards, no sweetness. This is time to just tell her. Be the parent.
try music in the shower
Maybe just explain to her that she is getting to be a big girl now and that she needs to take care of her self?
I never had a choice!
Wow some of these comment… Wow… She a 6 yr old Child… God help Poster when she becomes a lazy spotty teenager ! Take responsibility as a parent… Shaming a 6 yr old baby / child,. Is Abuse.
My kid was similar he dislike showers n brushing teeth however I made it as routine after he gets home to put his lunch box on sink shoes stays outside and straight in shower so he is got no excuse/reason to forget and if he cames put without washing his hair roperly he gets send back in again otherwise he doesn’t get to do anythng else until he is shower started when he was 5ish lots reminders after and still doing it he is almost 12 so he try to change the game when possible however got to be firm with no options available
Great question, a lot of children that are Neurodivergent (for example) in anyway can struggle with body hygiene, and not waiting to or lacking the motivation to do it. As someone who did struggle with this all I can say is keep up up with trying to make bath time seem more fun and less of a chore and less of huge stress/task. A lot of of people that are neurodivergent can get overwhelmed with all steps that are required, or they may have a hard time remembering all the proper steps. So maybe making a detailed list of things she would need to do during bath time. She also is 6 so just helping her with everything is also the best advice I can offer. 
best of luck mamas!
You’re the parent! Control your child! No more sweet talking, set up expectations and when they aren’t met, remove a privilege. Rewards are only for above and beyond expectations. This is known as teaching!
Take her to see how the homeless live. Maybe she just needs to see what a privilege it is to have that opportunity. I’m not saying that’s the way to go but it might make a difference
Shes 6 most kids her age do these kinds of things . Theres no negotiations on this even if she throws a fit . The more she does the more shes going to test you when she starts to complain just go about running the water and setting her toothbrush. After she finishes praise her for listening. She will soon understand that theres no use in throwing a fit because she wont get her way .
Take her outside and hose her down with the garden hose. You’ll only have to do it once. A hot bath is much better
Shes a child. They dont care period. Dont cause her anxiety or to be self conscious about it.
My younger brother wouldn’t wash and his hair smelled like sour milk ewww i took him in bathroom and dumped water on his head
I always tell my kids to make sure they’re clean because if they smelled they will get a bad nickname that will follow them all through the school year’s
I think there’s a special pens and soap art and things for bathrooms if she likes to draw also maybe her dollies all need a bath and they want their hair washed and you can help her braid it… If you live in a cold place it’s important that there’s some kind of heater I know getting out of the bathtub was terrible as a kid even in California…If She got your attention and you were willing to read her a story she would do it maybe find out what makes her happy and then bath time is The Big Happy Time… A very hot terry cloth robes straight out of the dryer tons of hugs and kisses and loves cuz she’s all clean clean baby clean… She’ll be asking you when she can take a bath if there’s that much love and attention and then bath time becomes her favorite time of the day… Dollies like tea parties in the bathtub and you could play tea party… My kids wanted me to wrap them in swaddling I would take a blanket and wrap them up like they were a baby even though they weren’t they outgrow all that but crazy love baths to this day they’d stay in there all day if they could because it’s associated with so much affection.
Talk to her about hygiene and why she needs to practice good hygiene. Let her know that it’s offensive and people will offend her if she has bad body odor.
Ask her if she wants to be the smelly kid at school that everyone runs from and talks bad about.
Then you can make bath time fun with bubbles and toys. And after bath time a routine of brushing teeth, putting on lotion and deodorant, and combing hair. If you have to make it a spa day in your home everyday with both of your daughters until it becomes a habit, it might help.
For morning brushing, try doing group brush where everyone brushes at the same time. My son had to do that morning and night with my grandson. Mom, Dad, sister, and baby brother all brushed teeth together, making it a fun family activity. He was younger but it might work for your six year old too.
Tell her what to do and follow through.
I had this problem with sons for a short time. Until I made them smell their dirty socks and underwear. Problem solved!!!
I do not bathe everyday as my tub doesht drain well and has to be scouped out after every use. So i do those wash cloth things that you can wipe off with
Maybe that would work for her ?
Have you tried making it a rule, with consequences if not followed?
You give her no choice but to do it
All it takes is someone not you mentioning how funky her teeth are.
Problem solved…
They need routines. I’m no expert but we have them.
Play with make up dress-up, try cooking give her some incentive
By example, as with everything else.
She’s 6 just put her ass in there and she’ll learn eventually
It comes with time. She’s 6. Not 16. Just run the tub water and put her in it. She’ll care later.
All kids are different, put her in the tub and wash her if she refuses, she’s only 6 for Pete’s sake.
She should developed routine until age of 6 . Go shower before bed brush teath and also developed morning routine . So it’s mom
Does she prefer showers or baths? Help her out
Tell her it’s either a nice warm shower or the garden hose. Her choice.
She’s a baby, not a lady yet. She needs help from a good Mother 
Erynn Servos Cormier
Omg
My brother is five and does things like this sometimes
Maybe just stay on her ass about things
Take away things that are important
Or even take a shower or bath with her…
Or even just sit in the bathroom with her
Maybe all she wants is company…
You are the parent. Shout at the child to bath. This isnt a democracy.
We always have bath morning every other day before school. I wash there hair and help with cleaning. Mine love to get messy outdoors so sometimes more. We also let them pick there own toothbrush out at the shop which helped encourage them. My little girl 5 likes to play with barbies and the hair washing jug in the bath😂 my son is 7 he doesn’t like bath time but he knows he has to so we just don’t mess about and he’s in and out once he’s clean xx
I never had an issue with my daughter bathing but brushing her teeth was quite the battle. After a trip to the dentist where I got scolded for not brushing her teeth for her, I’d had it. I found all sorts of the grossest pictures of rotten teeth online & printed them. Every time she argued with me about brushing her teeth or tried to get away with not brushing…I got the pics out and told her that her teeth were going to turn out like the ones in the pics. It took 2-3 weeks for her to get it. After that, I never had an issue with her brushing. She’s 20 now and still talks about those pictures being the reason she takes such good care of her teeth.
My six year old loses one of her treats if she refuses. She happily goes for a bath now on her own and often has one with her baby brother if he has one. It’s all about perseverance
Just make her do it. She is 6, not 16. Don’t give her a choice. Hygiene is something way too many people lack these days and it’s likely because they were not made to do so as a child. Just make her shower, make her brush her teeth. Make her shower nightly until she complys without a fit. She is still young enough that if she refuses, you put her in and you wash her. Sometimes with my 5 year old, that’s what it takes and he HATES it. But the next night he doesnt put up a fight.
Let her take a shower instead of a bath …
Off topic a bit, but if you compare the two and milestones like this, you are setting yourself up for undo stress, and them up for intense sibling rivalry.
Every kid is different. She’ll get there.
It reminds me of a quote I saw once,
If you’re teaching a student the same way over and over and they still don’t understand, the student isnt the problem. Change the approach.
Still fighting with my 17 year old…
You are the parent. Hygiene isn’t optional. TELL her to take a bath…period
I have a soap dodger too, he’s 5 and really sweaty child (always has been so hes in the shower 3/4 times a week at the least) I tell him just a quick shower and he is literally in and out in 5 mins, it takes him longer complaining about it than it does to shower him
So- some kids just don’t care. Usually they bounce back near high school (you pray). We are on the bounce back as we enter 7th grade but it’s still hit or miss.
Dollar store/Walmart sell those light up tubes that you crack and wear as bracelets - I forget what they’re called. Get the smaller, stubby ones, crack them and toss in the bath with her.
It’s fun! And cheap
My kid is 4 and has been taking baths in the dark for a year…lol
**I leave the hall light on
I am a clean freak and just a very clean person in general, I take great pride in my appearance and the appearance of my home. My kids are the exact opposite, my daughter is better than my 2 boys, but my kids would live in a barn and smell like one too if I didn’t constantly tell them to change clothes, take showers, brush their teeth and their hair, pick up their trash, change their sheets, ect. Idk how or why they are like this because they definately didn’t get that from me and not learned that by my example. I know that until I got sole custody of them 2 years ago their father on his half of the week didn’t make them clean their rooms, take showers, brush teeth, have bed times, eat veggies, drink water… none of that. I am afraid that those years we shared custody did a number on them. Not sure what to do about it either. You children will make their own minds up about things, that’s for sure!
My 9 yr old has the same issue and its been something that has been a constant struggle since shes been old enough for showers, we tried all the stuff you have and nothing works. The thing i have found to be easiest is to have it scheduled in her day. Since covid, the battle has been easier because she comes home every day and has to shower before she can touch or play with her little brother so its almost second nature at this point because its been part of her routine for over a year now and she is adament about wanting to physically attend school since day one. She doesn’t get rewarded but she does get punished if she gives me grief about taking a shower, teeth brushing is not issue…its definitely the showering thing…i take things away like no i pad for the night and the whole next day or no tv for bed that night if she gives me grief or attitude about it because it is something that we have no control over and it MUST be done…its fact of life, i give her a break on fridays and saturdays but she has to take one sunday night…she only has to wash her hair tuesdays, Thursdays and subdays. If she was swimming i give her a pass and let her spay her hair with spray conditioner…
Have you tried letting her pick out her own tooth brush and tooth paste, and even her own shampoo and conditioner, letting them help pick it out can help make them want to use it. Just an idea
Ask her what she would like that would make it more fun. It gives her some control and then it will be more motivating
My 6 year old fights me tooth and nail for EVERYTHING…At the end of the day I’ll pick her ass up like a sack of potatoes and put her in the tub/shower. If she refuses to brush her teeth, then I’ll do it for her otherwise it doesn’t get done. Rewards and taking things away didn’t work for us. So we just do it whether she likes it or not. Yeah it sucks because she’s crying and throwing a fit but oh well. It has to get done one way or another 
Don’t give her an option, you’re the parent. She’s 6.
So who’s the adult here. Make her do as she’s told. Your house. Your rules.
Show her some bad teeth pictures. Gum disease ect. I would only focus on the teeth. The body naturally cleanses itself.
Straight up tell her… if you don’t wash your gonna be the stinky kid
You make them. Parent you are the boss.
Well if you don’t know than I think it’s a lost cause
