Onesies are cozy and functional; thus, they are frequently worn daily. These items are essential parts of their outfit during the 1st year of a child’s existence. 

You may quickly and easily unfasten the diaper by using buttons. These garments are either thin or warm and appropriate for various seasons. These Onesies are multipurpose pieces of apparel that go well with a short, skirts, or pairs of pants, among other things. 

So when should babies stop wearing onesies?

Well, it doesn’t have a clear-cut answer. But, after one year, kids become more vigorous and active, mainly self-propelled walking, learn to use the bathroom, and occupy much more time. 

Therefore, it might not be as convenient to allow babies to move & be active when wearing a bodysuit. However, this clothing collection has styles for older kids and even grownups! 

As a result, bodysuit-wearing is an option for the entire family! 

These indicators can help you decide whether your baby must stop putting on onesies. 

1. Aesthetic 

Baby clothing choices are up to the parents. Onesies are unquestionably a lovely alternative for newborns. Some parents, however, think that a baby can quickly outgrow a onesie. 

Mothers who claim they enjoy seeing their babies’ chubby little things in these onesies can be found posting in various forums. Babies will inevitably outgrow their babyish features. 

For numerous parents, their kids must wear clothes they like. As a result, many parents decide to change up their children’s wardrobes as soon as they are roughly 1-3 years old

For guys, this wardrobe may comprise shirts and shorts, whereas, for girls, there are dresses. Toddlers could still sleep in onesie pajamas even when they have changed into different garments for the day.

2. Potty Training 

The start of potty training is perhaps the most frequent explanation for why parents start weaning their infants from onesies. 

A child’s potty training and exercise are significant life achievements. Children who are trained to use a toilet by themselves, usually between 18 and 24 months, can urinate and defecate in one. 

Onesies can merely add to the difficulty of potty training, which can be a very challenging time. For starters, it might be difficult for kids to open the bottom clasp of the onesie by themselves. 

Additionally, full-length onesies must be removed for a youngster to undertake potty training. Thus, it gets annoying to wear onesies at this developing time.

Children switch from onesies to pull-down clothes when they learn to use the toilet. Although traditionally, this would be a shirt & shorts, few parents prefer to make their kids wear pants specifically for training as they adjust. 

Training pants are an incredible way to transition kids from diapers into underwear. They are just like underwear but have additional fabric coatings for absorption in their crotch area. Accidents are accommodated by the extra padding, which nevertheless feels like a mature pair of kids’ underwear. 

3. Walking 

Parents frequently abandon onesies since their children have started to walk. Babies can take a very long time to learn how to walk. It might be between the range of 8 and 18 months because babies grow at their rate. 

However, by the time they are 12 months old, most babies can walk a short distance on their own. 

While it’s understandable for parents to rejoice when their children learn to walk, onesies might complicate things. 

Onesies could be simple to put on a newborn, as already said. That applied primarily to infants who were lying on their backs, though. It might not be easy to hold down a baby when they first start to walk and roam around. 

As a result, parents must adjust and create a strategy for clothing their infant while standing.

Unfortunately, it would be challenging to outfit a baby that’s standing in a onesie. A baby could now quickly get away with wearing nothing but a shirt & diapers. 

Parents shouldn’t have trouble dressing or undressing their infant while standing up if they have a shirt and diapers. 

Onesies with feet that are the whole length could also provide a slip risk. Let your infant practice walking barefoot to have adequate traction with the ground.


Can Babies Sleep In Onesies? 

Yes. Onesies are a cozy and cuddly alternative that is ideal for bed and naps. Consider wearing a onesie over a sleepsuit or regular pajamas to keep your little one warm if you live in a colder climate. 

Onesies make the perfect sleepwear if it’s warmer where you live. Additionally, they offer quick and straightforward access for changing and aid in keeping your baby’s diaper in place.

Why Do Infant Onesies Have Shoulders That Overlap?

Onesies’ overlapping shoulders are a clever design choice. By pulling the onesie over your baby’s body rather than their head, you can accomplish so thanks to these overlaps. It is ideal in a diaper explosion or if your child dislikes having clothing pulled over their head.

Should A Baby Wear Onesie All The Time? 

When a baby should quit wearing a onesie, the parent has a different opinion. While some wear them only for nighttime warming, others use them until their kids start walking (which might take anywhere from 8 to 18 months). As far as they are in diapers, Try keeping your newborns in onesies.

Can Babies Sleep Without Onesies? 

Baby clothing should resemble that which an adult would feel at ease wearing in the same environment, according to the American Academy of Pediatrics (AAP). So, in addition to what a grownup would wear, you might give them one more layer, but not more.

Can A Baby Sleep In Just A Diaper? 

The AAP advises putting your infant to bed in only light clothing. However, according to the Foundation for the Study of Infant Deaths, it’s acceptable to let your baby sleep in nothing but his diaper during hot months. 

A newborn, however, will require one further layer of clothes than you do because they usually prefer warmth over cold.


As much as parents may consider a variety of considerations when deciding when to stop wearing onesies to bed, convenience is ultimately what matters.

Onesies could be pretty practical as a kind of clothing for a newborn baby because they are simple to wear and take off. 

Once the infant starts to stand & walk, the convenience begins to decrease. When the baby is wearing a shirt and diaper, looking for a nasty diaper becomes much simpler because you can ensure it isn’t dirty by looking directly rather than needing to smell the baby’s butt. 

Onesies create a barrier during potty practice/training, too.
