What Is A Onesie?
A onesie is a short-sleeved shirt that covers the baby’s entire torso. They can also include pants or leggings that go over the top.
It’s like a regular t-shirt with sleeves on the bottom and a clasp to do up at the bottom. There are different styles available, depending on whether you prefer fitted or loose.
The most common onesies are made from 100% cotton and can even feature a zipper in the back.
You may see some options made from polyester blends, which tend to feel softer than pure cotton. Some brands offer stretchy versions that will fit snugly around your baby’s belly.
How Long Does It Take For Them To Outgrow Their Onesies?
The average length of time babies will wear a onesie is about three months. Some babies grow out of them sooner than others. However, there are no hard and fast rules.
If you’re not sure, just keep an eye on your child’s growth and make adjustments accordingly.
It also varies by brand and style, some babies grow out of their onesies around three months old but depending on the brand a lot of them grow out of them at six months.
If you’re planning to purchase a few sets of each size, you could save yourself some money in the long run by ordering in bulk.
The best way to find out if your baby is growing into his or her onesie is to measure him or her regularly. Look for changes in weight, height, and overall proportions.
Once he or she reaches the age where the onesie doesn’t fit properly, you can consider switching to another style.
So When Do Babies Stop Wearing Onesies?
There isn’t an exact age when your baby stops wearing his or her onesie. However, there are general guidelines as we have already mentioned.
Most babies who aren’t born prematurely will grow out of their onesie between 3 and 6 months. Those who were born early (before 37 weeks) usually outgrow them at 4 months.
If your baby is still wearing a onesie after 6 months, you may want to consider getting him or her a sleeper instead. These sleepers often come in multiple sizes, making them perfect for newborns through toddlers.
If your baby is already older than 6 months, you may be able to switch to a zip-up hooded sweater.
Hooded sweaters are great because they cover your baby’s head and neck while keeping him or her warm. They also provide extra protection against wind and rain if you take them outside wearing them.
You’ll also want to judge it when you start potty training. For example, when this happens, you might want to change your little one into regular clothes like t-shirts and shorts as this makes it easier for them.
Onesies with snaps underneath make access difficult in the training period, and getting them out of this helps them develop independent habits of undressing themselves.
Choosing regular clothes over onesies is also a good idea when your child starts to play outside and gets muddy.
This means you need to wash your children’s clothing more frequently and you’ll need them to be able to just whip a t-shirt off and pop it in the wash, instead of unbuttoning a whole onesie.
It’s also easier to stop a child from wearing a onesie when they start walking as they can often now learn to get dressed without assistance.
Walking can happen between 12 and 14.5 months, and when they can walk themselves, they might be less compliant with nappy changes or dress changes.
If they squirm from your hands and run away when you’re helping them get dressed, onesies are not the easiest type of clothing.
It is also easier to take them out of onesies and use regular clothes when they are attending daycare, so educators and helpers do not have to just do the sniff test when it comes to who did a smelly poo!
There might even come a time when your toddler starts talking, that they tell you themselves they do not want to wear a onesie anymore!
When Should You Keep Your Baby In A Onesie?
In colder temperatures, onesies can be helpful to use as a layering clothing item, without being too bulky underneath normal clothes.
They can also make sure the baby’s chest and tummy are kept warm as they don’t ride up like shirts and other tops.
Once your baby begins to crawl, you might find shirts tend to ride up at the back and this might be why keeping them in a onesie is a good idea.
A lot of parents do not like having baby bellies on show, or diapers hanging out as the shirt rides up. If this is the case, a onesie can keep these areas contained.
However, if you have a tall baby, you might find onesies do not fit well and they reach the sizing limit quite quickly. In this case, you should move to longer t-shirts and shorts or pants.
What Kind Of Onesies Are Best For Newborns And Toddlers?
Most newborns are too small for traditional onesies. Instead, look for onesies designed specifically for newborns.
These typically feature a soft material like fleece, microfiber, or terrycloth. When choosing these types of fabrics, remember that they will likely shrink during washing.
Be sure to wash them separately so they don’t lose any of their softness.
Toddler onesies tend to be made from cotton, which is easier to care for. Choose onesies with elasticized cuffs and waistbands. You can also choose onesies with snaps or buttons to help prevent accidental openings.
How Long Should A Baby Sleep In His Or Her Onesie?
There is no set time limit on how long a baby should wear his or her onesie overnight. It depends on two factors:
Your Baby’s Sleeping Position
Some babies prefer to sleep face down, while others prefer to sleep on their tummies. You need to ensure they are in a position where it cannot be unbuttoned if they are sleeping in their onesie overnight.
The Temperature Inside Your Home
If you live somewhere cold, you may wish to keep your baby bundled up all night. On the other hand, if you live somewhere hot, you may find a onesie is enough to last them through the night.
This means during the summer, you may want to leave your baby in his or her onesie until he or she falls asleep at night. However, during winter, you may wish to bundle him or her up warmly.
Do Your Research Before Buying Baby Clothes
Before you start purchasing any items for your baby, it’s always helpful to research the type of clothing you’re looking for. You’ll want to know what fabrics and materials are used, how durable they are, and more.
There are plenty of online resources that can help you learn more about these things. You can also check out online guides to choosing the right baby gear, and you can speak to family and friends that have had to buy baby clothes for their children before you.
