Looking for answers on when do babies stop wearing onesies and start planning yourself indignance?

Onesies are a full-body suit-like type of clothing for babies.

They have two openings at the bottom for the baby’s legs and, in most cases, a set of buttons at the bottom. 

It’s like a cute form of jumpsuits for babies. They are famous for babies because of their extreme comfort and warmth.

However, your little one will not be wearing onesies forever. So, when do babies outgrow onesies? 

When Do Babies Stop Wearing Onesies? 

We can’t deny that onesies look cute on babies. They are also comfortable, stretchy, and safe because they don’t cover the baby’s head during sleep.

But, unfortunately, you can’t dress your baby in onesies forever. 

Well, onesies come in two sizes are 2 and 3. Unfortunately, once your baby outgrows size 3, there isn’t a size 4 onesies in the market that you can turn to. 

As to when exactly a baby will stop wearing onesies, it’s a personal choice, depending on your baby’s growth rate. 

Averagely, most babies will stop wearing onesies at some point between 12 months to 24 months.

However, other factors can make babies stop wearing onesies at any time, including:   

1. Nappies

Most bodysuits have a design that snaps underneath, which is important in containing leaks when using disposables. However, for cloth nappies, it’s a bit different. 

Bodysuits, especially those that are close-fitting, can cause compression leaks by pressing in on the nappy.

When the baby is using cloth nappies, you should consider using usual clothes instead of onesies. 

2. Potty Training

It is effortless to pull down shorts together with the nappies or undies during toilet training compared to struggling with undies before sitting on the potty. 

During potty training, most parents prefer dressing their young ones in shorts and t-shirts because it helps reduce stress when undressing and makes the training easy for the baby.

3.Walking Stage

Some parents may stop dressing their babies in onesies when they learn how to walk on their own.

The age of independent walking differs from one baby to another.

It can happen as early as 8 months or as late as 18 months, but most babies will be walking from 12 to 14 months of age on an average scale. 

When the baby starts walking, they may become a little stressed and less compliant when changing nappies and getting dressed.

For a playful child, it’s a bit difficult to get them to put on onesies compared to how it can be easy for them to be dressed in skirts or shorts before they slip out of your arms. 

4. Age

Not every parent wants to have their baby’s belly exposed.

Onesies do a much better job at covering your baby than any piece of clothing, especially when you are outdoors.

But when your baby starts growing, you might not have any other choice than to leave onesies behind.

For example, your baby might be taller than their age requirement, meaning the onesie will not fit them comfortably. 

5. Temperature

One of the best reasons parents prefer using onesies is because they keep the baby.

That means they might be your go-to piece of clothing during the cold weather.

But, when it is summer, or the weather starts getting warmer, many parents prefer putting onesies aside.

The intense heat will make the onesie pretty hot and uncomfortable for the baby. 

6. Toddlers Opinion

Believe it or not, there is a time when babies start having opinions about what they like.

They might not be able to speak it out loud, by their behavior is an excellent mode of communication.

If your baby becomes fussy when dressed in onesies, there is a possibility that they do not like it. 


Yes, your baby might look all cute and comfy in your vast collection of onesies.

However, what many parents do not know is when do babies stop wearing onesies.

Well, once your baby has outgrown onesies or is no longer comfortable in them, maybe it is time to pack them.
