Babies Stop Wearing Onesies Sooner Than You Think!

It's easy to assume that babies need to be bundled up in layers, but the truth is that they're warmer than you think. 

Putting babies in too thick clothes can make them uncomfortable, not to mention overheating them and making them more susceptible to respiratory infections. So why not make it as easy on yourself as possible? 

By knowing when babies stop wearing onesies, you can be ready to move on to the next stage of their care!

What Is a Onesie?

A Onesie is the shortened name for a Onesie, a full-length onesie. They are typically worn by babies and little kids who cannot dress themselves. Basic Onesies come in various colors, shapes, and patterns to fit everyone's taste. 

But when do babies stop wearing them? When they start walking, that's when. Unfortunately, many parents find this out the hard way as they walk around their house looking for their child, who has taken off their onesie and is running around without any clothes. 

Thankfully, pullover onesies offer more coverage so your child can still enjoy them even when they're too big to wear as a full-length garment.

Why Do Babies Wear Onesies?

It's tough to say when babies stop wearing onesies because every child is different. Some are content in their onesie as they learn to walk, and some aren't until they start wearing t-shirts and jeans. 

But it's safe to say that most children stop dressing like a baby when they can walk alone, somewhere between 12-18 months old. So the widespread popularity of baby onesies is completely justified, given their multiple benefits. 

Why Do Babies Wear Onesies?

Some parents might think babies are too young to wear clothes; instead, they will dress them in an undershirt and a onesie. 

The thought process behind this is that a baby can't tell the difference between cold air and hot air, so it's better for them to be as warm as possible. However, here are some reasons you should get a onesie for your little one.


Even though kids grow out of them sooner than we think, at least for now, there are still many practical reasons why it's worth investing in a few good onesies. 

Not only do they make diaper changes easier, but they also make getting dressed an easy task when your little one is just learning to put on their clothes or shoes without help.

We recommend you purchase a basic onesie for baby clothing, for their snap-open snap to keep them secure. In addition, they stretch around the baby's stomach and chest, providing a soft and comfortable shirt layer.


With all the messes babies are prone to, they need to wear something that doesn't get dirty quickly. 

So if you need a quick change before heading home after lunch, you'll be glad you remembered your sweet baby's onesie instead of a dirty shirt or dress. 

As any parent knows, Gerber onesies are indispensable when potty training starts because they make changing messy diapers much easier!


One last benefit of wearing onesies is how much safer they are for crawling infants. They may not look like much more than oversized shirts, but baby onesies have long sleeves that protect infants' delicate arms from the hardwood floor while they're learning to crawl. 

In addition, parents have devised ways to make these simple garments much cuter by adding appliques or patches. 

How Long Do Babies Wear Onesies?

A baby typically wears a onesie until they are about six months old. Once they've outgrown the length of their onesie, you'll want to move them into a sleep sack for safety reasons. Babies can't kick off their blanket as easily in a sleeping bag. 

If your child has been sleeping through the night without waking up, it's time to switch them over to pajamas or footed jammies at bedtime too, so they're not wearing an extra layer all day long while napping.

When Should Toddlers Stop Wearing a Onesie?

Some parents believe that it's time to put their baby in a real shirt once they can sit up on their own and show signs of interest in dressing themselves, but the truth is that babies stop wearing onesies sooner than you think. 

The average age at which babies stop wearing onesies is around 10-12 months. Although some children can walk at this age, others will still use the support of a parent's arms to get around. Either way, they're ready for more independence in their clothing choices. 

What Do 1-Year-Olds Wear?

1-year-olds typically wear 8-month-old clothing. This is because they are still too young to walk around without the help of their parents or caregivers, so they need clothes that are easy to take on and off. 

This means onesies and pants with elastic waistbands that can be pulled over a child's head without pulling it over the child's feet. These also make diaper changes easier. But don't worry, baby won't always want to wear these outfits forever!

When Babies Stop Wearing Onesies? 

An easy answer would be a few months old or when they grow out of them. But the truth is that this all depends on their size. Some babies could wear them for a year or more, while others will grow out of them within a month or two. 

So if you're buying for a friend's baby shower and aren't sure what size the parents are expecting, it might be best to ask. The last thing you want to do is buy something too small. 

In addition, many parents get rid of their baby clothes before the child grows out of them - so if they've received enough clothing as gifts and need nothing else, it might be worth checking with them first.
