When's the appropriate age to stop using a onsie under clothes?

I'm one who overdresses because I'm cold myself. Plus, I'm afraid of how delicate a babies skin is to certain clothing. BUT when is a good age to not have to worry about adding a onsie under pj's or other clothing?...I know the rule of thumb for a newborn is to dress them in one more layer than you would wear, but for how long?

When my daughter was born (in July in KS), the nurses could not understand why I always took her out of the swaddling blanket. In my opinion, she was hollering because she was too warm. Once I took her out of the blanket and just laid it on top of her she calmed down. From then on, if I was chilled and when I added a sweater to me I added one to her. If I was warm, I checked her.

Onesies are great underwear (I assume you mean all in one vests with the popper undercarriage?)....make up to 36 months (Mothercare do anyway). Saves on separate underwear (pants and vest) if weather means you need underwear. When you need to stop is potty training when speed is of the essence and when they need to "feel" grown up in their pants. Other than that use as you see fit regardless , I still reckon my 3 year old needs an extra layer as they are still so delicate ......x

Usually, if a baby is uncomfortably hot, s/he'll let you know - loudly! If you notice the child fussing a bit more or turning red or whatever, peel off a layer and see if it's more comfortable. My son quickly learned to wriggle out of his own clothing when he was hot (we live in Texas, so it happened often), so by the time he hit about six months, he was generally stark naked. He was happy and it saved me a lot of money on clothing :D

I never heard the "one more layer" recommendation; our pediatrician recommended dressing them the same way we dressed ourselves. I read you should judge the baby's body temperature at the back of their neck.

I only used onesies as I did undershirts. Once they potty trained onesies were no longer convenience.

I guess for the first few weeks I'd put my babies in gowns cuz they like being all bunched up, but after that it was real outfits and if needed a onesie but she usually sleeps in a onesie cuz being all smooshed up next to me in bed gets her hot!
Eric slept in a bassinet so he wore thicker footie pjs, but with bed sharing Fierna has to be just in a onesie.

My daughter is 3 and has always worn an undershirt, camisole or when she was younger, a onesie, underneath her clothes. Though all are cotton, many of her clothes have embroidery on the front or labels in the back and the undershirt prevents chafing or itching from them.
I remember, I wore an undershirt under my clothes until I was 13 and switched to a bra...

till they stop fitting lol my youngest still wears them an shes 2 yrs old but thats because she takes off the rest of her clothes but can't seem to figure out the onsie

Eh, it's really one of those things that's "to each his own".
My son is actually 3 and I still use a onesie on him at night. ;) If I don't he'll have easy access to his penis and pull it out the top of his pj's. I just potty trained him so prior to that it was a real pain in the ass because he'd wake up wet because he had pulled his penis out and then peed sometime throughout the night.

Tonight is actually the first night he's gone to bed without one in a while. His diapers are always dry in the morning but, my luck, he'll have yanked his penis out and he'll pee. lol

I heard dress them as you dress yourself, but everyone is different. I'm generally cold if it is under 75 degrees. We live in San Diego, so it is a pretty mild climate, but it does get cold here (for our thin Cali blood). In winter I used them under feety PJ's untl they outgrew them and I knew they'd keep covers on. I'd even put socks on under the PJ's... In the summer, sometimes they'd only wear a onsie when it was hot.

Then we went to the sleeveless undershirts. One of my 3 boys still wears those under his Tshirts by choice, even during the summer.

I never put a onesie under clothes.. but I live in San Diego... I am not sure where you live...

We stopped using onies around 6 months. Our son was born in October so by the time he was 6 months it was spring and warm so I was not worried about him getting too cold. Plus they were a pain anyhow. We never used them under pj's.

Melissa - posted on 08/18/2011




i used them all the time in cold weather for my son up to the time he outgrew onesies, then i switched to undershirts, he is now 5 1/2 and i still use undershirts when it is really cold in the winter. Just as extra protection. It gets really cold where we live so during winter months, i would rather dress him a little warmer. I don't usually use them in the fall now. However, i think i stopped using undershirts and onsies regularly at 3/4 years old.

In winter when Logan was a baby he'd wear a onesie with overalls and a jumper or pants and a jumper and a singlet under the onesie.

Stifler's - posted on 08/18/2011




In summer my babies get around in only a onesie/clothes with no singlet or just a singlet and nappy. Logan got to about 1 we stopped using onesies and he just wears t -shirts and shorts/pants and a jumper if it's cold.

Ethan wore his consistently up to this spring, so about 17/18 months but that's only because he has raynauds syndrome and we had to keep his core temperature up to stop his hands and feet going blue with cold. We stopped using them under clothes altogether (unless grandma dresses him my mil is obsessed with keeping him warm) at about 20 months when our weather got warmer and now at almost 22 months we are only using them at night (as pjs) because we are potty training and they get in the way of his big boy pants.

Poppy on the other hand often doesn't wear anything under her outfits because the weather Is warmer at the moment and so she doesn't need them.

I let both the kids sit around the house in one though regardless of the weather because if it's cold the heating is on and if it's warm they don't need clothes.

Eric always wore a onesie under his clothes unless the shirt had snaps under the crotch until the summer he was 2, this summer!
It's not for warmth totally, I also do it so his diaper isn't showing and so his back doesn't get scratched up going down slides or in his carseat.
I haven't seen them sized bigger then 24 months and he outgrew those ones so that's why this summer I stopped.

I live in Hawaii, so it's pretty rare that I ever put a onesie UNDER clothes.... ;)

I did use them frequently for the first year-ish though... and my son had a few (though mostly regular shirts) til around 2.

We used onesies all by themselves, but then we live in a hot climate. Once our kids were starting to dress themselves we stopped with onesies simply because the kids couldn't snap the snaps. Since our kids were in a Montessori school, that was at about age 18 months.

Caitlin - posted on 08/18/2011




I never used one, never knew you were supposed to.. Lol? Well, considering for the first 4 months or so they pretty much stay exclusively in footie pjs, they aren't really needed. If we go out, there are blankets or snowsuits if it is cold enough, and those go over the footie PJs. I could see them as useful in the summertime, and I sometimes used a onesie as a top with a pair of pants, but honestly, I prefer the t-shirt look witht he little belly poking out! My kids also hated shoes/socks, and refused to wear them out until they were walking, so even in very cold weather, they were shoeless/sockless (or in snowsuits). Not always by choice though, they just always took them off.

I used onsies for about 2 months. Then I used them under pants only (like a shirt) when my daughter was 1 and 2.

[deleted account]

I never put onsies under clothes. I didn't even know people did that. But I live in a mild climate.

Katherine - posted on 08/18/2011




Honestly I HATE onesies. When my kids were newborns I dressed them in them, but now no way. My daughter is 29 months and potty training so it's a pain in the butt. They actually make them to 36 I've seen.

I just plain don't like them.

**Edit to add I think 12 months is good.

I found them conveinent from birth to 6 months. But sometime pass that (usually when they learn to crawl and are on the go). They become pretty annoying. Some babies are hard enough to get to sit still for a diaper change without having to worry about extra snaps.

Just go by the skin on the back of their neck if you worry about over dressing them. If it feels hot, strip a layer off.

I'd say if you live in a very cold climate, you have to worry about this more. Or a very hot climate you have to worry about them being overdressed.

If you have air conditioning in the summer. I worry about my kids getting too cold at night. So I just put them in thicker jammies. But you have to be extremely careful... overheating a baby is very dangerous and they usually get hotter when they sleep.

Unless you live in an extreme climate. I wouldn't worry about it too much. And I'd say by the 6-8 month mark you're pretty safe for stopping the extra layer. (Unless like I said, it's extremely cold out)

I stopped using them under clothes on Emma when the weather warmed up. She would have been about 9 months. I didn't really use them under jammies ever.

Nikki - posted on 08/18/2011




I think it depends, personally I hate the darn things and as soon as my daughter started fighting me every time I dressed her (10 months) I gave up using them. At 22 months she would still fit in them but she still fights me every time I have to dress her so they are just not worth the tantrums and hassle.

Mary - posted on 08/18/2011




I don't think there is any hard and fast rule. My daughter was born at the end of November, so I used them all the time for about the first 6 months, but then it was summer here, and much to hot for layers of clothing, particularly when we were outside. By the time it was cold enough to consider wearing them again, it just seemed pointless to me. She was a year old, and walking, and quite frankly, the thing that seemed to bug her most was being too hot, so I never went back to them.

Becky - posted on 08/17/2011




I've never used one under jammies, unless maybe we were camping or something, because we keep our house quite warm at night. Even during the day, I only used them under clothing is we were going to be outside for a bit and it was cooler out. And I did that probably up until 2 or so, when they got too big for onesies. But by 2, it was really only if we were going to be out in the cold for quite a long time. I think probably once they're mobile- say around 7-9 months, they are more likely to stay warmer because they're moving more, and you probably wouldn't want to use one unless it was quite chilly.
I used onesies a lot when they were infants, but more often just as a shirt on it's own or by itself around the house or in hot weather, than as an undershirt.
