As a new parent, finding the right clothing for your little one is always a top priority. And when it comes to comfort, versatility, and practicality, there’s nothing quite like a baby onesie. But with so many options on the market, how do you choose the best one for your baby?
When it comes to selecting the perfect onesie for your little one, two factors are crucial: quality and design. Quality onesies are made from soft and breathable fabrics that are gentle on your baby’s delicate skin.

In this article, we will explore the best baby onesies on the market that meet both of these criteria. Whether you’re looking for something simple and classic, or fun and whimsical, we’ve got you covered. So, let’s dive in and find the perfect onesie for your little bundle of joy!

What Should I Look For In A Onesie Baby?
Look for onesies made from soft, breathable fabrics that won’t irritate your baby’s delicate skin. Natural materials like cotton, bamboo, or organic cotton are excellent choices (1). Quality onesies should be durable and long-lasting, able to withstand repeated washings and wearings. Check the seams and stitching to make sure they’re strong and well-made and make sure you choose the right size for your baby. Onesies that are too big or too small can be uncomfortable for your little one, so it’s essential to get the sizing right.
Is It Better To Hang Or Fold Onesies?
It is usually more practical to fold onesies, as this allows you to store them more efficiently and makes it easier to see all of your baby’s clothing options at a glance. That being said, there are some situations where hanging onesies may be more practical. For example, if you have limited drawer space, or if you want to keep your baby’s clothing wrinkle-free, hanging onesies may be a good option.
How Many Onesies Does A Newborn Need A Day?
Newborn babies typically go through several onesies a day, as they are prone to spit up, drool, and have diaper leaks. While the exact number of onesies needed per day can vary depending on your baby’s needs and your own laundry routine, a general rule of thumb is to have around 5-7 onesies on hand per day.
When Should You Stop Buying Onesies?
Most babies outgrow onesies by the time they are around 12 months old. As babies grow and become more active, they often need more freedom of movement in their clothing. At this point, you may want to switch to outfits that have more separate pieces, such as pants and shirts, that allow for greater mobility.
It’s also worth noting that some parents continue to use onesies beyond the baby stage as undershirts or as a layering piece in colder weather. So even if your baby has outgrown onesies, they may still have a place in your child’s wardrobe.
Do You Put A Onesie Under All Baby Clothes?
Putting a onesie under your baby’s clothing is a personal choice and can depend on a few factors, including the weather, your baby’s comfort, and the type of clothing you are dressing them in. The American Academy of Pediatrics (AAP) recommends you snap or zip all the way down the front, instead of the back and snap or zip down both legs to make diaper changes easier (2).
In general, it is a good idea to dress your baby in a onesie under their clothing, especially during cooler months or in air-conditioned environments. The extra layer can help keep your baby warm and comfortable and also provides a barrier between their skin and potentially scratchy or irritating fabrics.
Sizing Guidelines For Baby Onesies
Navigating the world of baby onesie sizes can be a bit overwhelming, as each brand and product may have slightly different size guidelines. To help make things a bit easier, here is a handy guide to common baby onesie sizes:
- Newborn: Typically fitting babies up to 7 pounds, this size may not be necessary if you’re expecting a larger baby.
- 0-3 months: Babies weighing between 7 and 12 pounds, and measuring up to around 23 inches. However, some babies may skip this size altogether.
- 3-6 months: Babies weighing between 12 and 17 pounds, and measuring up to 27 inches in length.
- 6-12 months: Babies weighing between 17 and 22 pounds, and measuring up to 29 inches.
- 12-18 months: Babies weighing between 22 and 27 pounds, and measuring up to 31 inches in length.
