Idk if anyone else deals with this but I gotta vent… my kids’ grandparents (both sides) think they know what size clothes my kids “should” be in… I am their mom & trust me… I KNOW what size they wear lol Like for Christmas last year, I told my mom that my son was in 5T… well, she tells me that they got him 4t stuff because my dad thought 5t looked too big… & guess what. NONE of the clothes they bought fit… then there’s my MIL… she brings me clothes all the time that she finds at thrift stores & every single one is like 10/12… my son is now 6 & wears size 6/7… so now he has a closet full of clothes that are way too big… I bet maybe 1/4 is actually his size. Don’t get me wrong… I am very grateful they buy my kids clothes sometimes, but they’re no good if they don’t fit 
Then when he spends the night with my MIL, I’ll pack his size clothes… he comes back every single time in a shirt that is literally to his knees… it drives me crazy. My SIL has also ALWAYS dressed her kids in clothes that are a few sizes too big. Idk if it’s just something they do or what lol like what are supposed to be shorts, looks like pants & shirts down to the knees.
Yeah I’d just pick through the ones i want & garage sale the rest as for clothes not coming back send 1 of those mesh bags for the dirty laundry. & Pack outfit by day maybe in those dollar store seal bags & have your don to only pull out what he’s wearing that day if that doesn’t work call and facetime them daily bitching 
That would drive me crazy! Just donate them. If they are new ask for receipt.
Well look at the bright side, the bigger clothes will fit him eventually so you box them up until it will fit. The stuff that is to small, ask where they got it and exchange it. If it’s a thrift store then re-donate to a thrift store or someone you know who could use them. I know the feeling because it’s happened to my son with toys and we usually end up exchanging or donating them but we always have him say thank you because at least they thought about him.
I always preferred clothes they could grown into, that way when they hit that growth spurt,I wasn’t having to go buy a whole new wardrobe for them 
My grandparents, specifically my grandma, (my sons great grandparents) always buy him the wrong size clothes. She also buys stuff or does stuff I explicitly say not to. It makes me crazy and I’m constantly fighting her on how to parent my own child.
I used to give away/ donate clothes that my kids grandma used to buy them that weren’t their style and sizes
My mother in law always bought things 3 sizes too big. “So they can wear them longer”
Well no, because it still only FITS for so long. I’m not putting huge clothes on them
My family does but I love it cus they always buy slightly bigger stuff so he can use it longer. My family up north though always buy too many pants and long sleeves like I don’t live in Florida lmao
Too small? Sell it.
Too big? Store away until he actually fits it.
It’s what I do here but never has my family bought clothes that were too small.
I love my relatives buying my son clothes he can grow into. If i want something in his current size i usually buy it.
I intentionally tell my parents and in laws his next size up. So even if it takes a while to get them theyre usually guaranteed to fit.
The bigger clothes I wouldn’t have an issue with, twice my 5yo has woken up and it’s like nothing in his drawers fits, so we’ve learned to buy ahead and keep a size or two bigger of all essentials. But giving kids clothes that are too small is just a stupid waste of money.
I would just accept the bigger clothes and put them away for later. Can definitely be a life savor. My son will randomly grow over night and one time he woke up in the morning and nothing fit because I only had His size. To small would annoy me tho. I like putting my kids in clothes that are to big for bed tho lol. I think it’s super adorable when my 2 year old runs around in big clothes, especially one of her brothers old shirts. My daughters wearing one of my boyfriends sons old shirt right now lol it’s 3 sizes to big
Better too big than too small. Personally I like having bins of too big clothes. I never have to go on a shopping spree if she hits a growth spurt cause I have enough of next size stashed away.
My MIL would always buy wrong size. (Even when I’d specifically tell her). I would return if could w/out receipts because she’d get put off when I’d ask for receipts. 
so I would just give them to Goodwill or 2nd hand store never worn.
Be thankful you have family who care enough to buy your children things. Not all grandparents care and some families don’t have any grandparents. If exchanging the clothes for the correct size is too inconvenient, then just donate the clothes to a local charity for children and know that others will enjoy the clothes.
I totally understand and I’m with you. If my kids need clothes, it’s definitely better to have the right size. If they don’t currently need clothes, then bigger is better to hang on to. But yeah I never like putting my kids in clothes that are way too big for them. We wouldn’t wear clothes 4 sizes too big, would we? So why should our kids?
Idk. Isn’t it just good etiquette to always include a gift receipt for clothes? I would just ask for a receipt if they buy clothes. I think that’s a perfectly reasonable request, but literally everyone I’ve ever known just does that automatically.
Just exchange what you can and put away the rest for when it does fit. Unless it’s super trendy stuff, it will still be just fine when it does.
Stop crying over petty shit. Be thankful and grateful people are even buying things for your kids. You sound like a selfish uppity brat
Its nice to have bigger clothes stashed away for later, thats always a plus.
But clothes that are too small are totally useless
I always ask for their sizes. I never assume. Kids grow fast.
My family used to joke that my son looked homeless in clothes that were too big, but he hit growth spurts so often. I couldn’t afford to replace his entire wardrobe every 3 months. I cuffed his pants on the inside and would only throw in 3 stitches so I could cut them later.
My family asks when they buy my son clothes but I have actually asked that if they are going to buy my daughter clothes that they buy 6 mos and up sizes only because she has so many that we were given in anything smaller. My son has one suit that he needs to grow into but it won’t be long before he is in it.
I buy my child growing into clothes all the time. But still close to her size, usually only a size or two up. Never 4 times the size!! Expect maybe shoes, jesus kid shoes are expensive!
My ex mil is very kind to get my son clothes sometimes but she insists he is a size smaller than he is. So the clothes don’t fit. His sister usually grabs the tshirts for bed shirts. He is a big boy and likes his clothes loose and I try to explain that but she is a stubborn women.
My MIL still can’t buy her son, my husband the right. Like we have been together 21 years and he still wears the same brand style jeans he did it high school. Farm boys style doesn’t very much!
I experienced this for years. A family member would give my son clothes for his birthday. Everything was always many sizes too large; and there were never any tags, or gift receipts. My tactful requests for a gift receipt went unanswered. They did this for years. Sigh…
Politely request gift receipts and explain why. They will get the hit eventually.
Just tell them to buy the next size up. Its not complicated…
Tell them they need returned. Maybe they will listen next time. Lol.
I always ask my daughter , but if I see something that might fit I get it. Some clothes are wrong on the sizes.
I love the " be thankful " comments. Like you are being ungrateful that you don’t want your children looking like bums and dressed nice in clothes that fit.
I would politely ask every time for receipts or for the tags to remain on the clothes for such and such reasons. Eventually they will start buying the right size clothes or stop buying clothes. Its nice they help, but its not helping if the clothes do not fit.
My sister does it with her grandkids.
If they are too big keep them. If they are too small exchange them if you know where thry were bought
As my mom use to say. It’s the thought that counts. Or their heart is in the right place.
Kids grow way too fast … I’m a mom who can’t even buy pants I guess … or I just have a stick child … I literally bought these pants maybe 3 months ago and they fit perfect… now they are high wadders… Lol it’s always alot easier to ask what preference you would want… maybe eventually they’ll realize when he’s not wearing any of them 🤷 a chuckle at my sunshines high waders if you would like ? Lol
Deny you know them. Tell them to eat shit and die.
Whatever makes you feel better. Do it yourself. Don’t accept any help from anyone. Get drunk and have 3 more. Try being bald. That’ll fix it.
My kids fathers side if the family do this! My son is in 6-7 and aged 5, they buy him 4-5 or 5-6 so too small. Or my daughter is in 3-4 and nearly 3, they will get her 2-3. This is after they have asked their sizing too, drives me insane!
I have always bought at least two sizes bigger for my children. The reason being that they grow so fast that they would not get enough wear out of anything. Just this past Christmas, I purchased, pants for my son that was two sizes bigger. This fall when he tried on the pants they were too small. So for me Bigger the size, the better. If your parents continue to buy sized that are smaller, give them sizes that are at least four sizes bigger. That might lead to them to correct size, I hope.
Take it back and get the correct size simple
