Every parent knows that onesies are one of those essential baby items that they cannot live without. Easy to wear and comfortable, they are also perfect for when you need a go-to base layer in chilly weather. But where do you start when it comes to buying onesies? This buyer’s guide for baby onesies has all the answers. 

What’s The Difference Between Onesies, Bodysuits,  Rompers, And Babygrows?

What Is A Onesie?

A onesie or a bodysuit is an outfit that fits over your little one’s diaper. They are usually fastened with buttons or poppers. Usually, onesies are loose-fitting and very comfortable for babies. 

What Is A Babygrow?

A babygrow or a sleepsuit is an all-in-one footed outfit that does away with the need for socks. Many babygrows also feature scratch mitts on the sleeves that can be easily folded over your little one’s hands.

What Is A Romper?

A romper is a one-piece outfit that has open hands and feet. Some rompers also don’t have legs or sleeves, which makes them a great choice for warmer weather.

Are Onesies Right For Your Baby?

There are many reasons why onesies are a must-have for any baby. Here are some of them: 

• They are great for the first year because they come in a wide variety of sizes from newborn to toddler
• You need several onesies on hand to help you get through the messiness that comes with having a baby. Babies need to be changed more than thrice a day. Onesies just make this process a lot easier. 
• They make great baby shower or birthday gift ideas
• Onesies are great for both hot and cold weather. They can either be worn by themselves when it’s hot or as a base layer when it’s cold. 
• Onesies fit well over diapers. They also come with fastening mechanisms that can open easily for quick changes.
• Onesies are great gender-neutral clothes. This means you can always reuse your onesies for your next baby. 
• Onesies are super versatile and can be paired with shorts, skirts, or pants.

Buying Guide For Baby Onesies

1. Size

Buying an adorable onesie for your little one only to find that it's too small is a disappointment many parents know all too well. You want to make sure that all the clothes you buy for your little one fit them well. This will not only be comfortable for them but it will also allow them to move around with ease. 

Also, remember that babies grow fast. Think about your baby’s upcoming growth spurts as you make your purchases. Most baby clothes have size guides to help you, so be sure to check these out as well. When in doubt, go for the larger size instead of the smaller one. 

2. Material

When your baby arrives, you’d probably want to dress them in cute, trendy outfits with a bunch of bells and whistles to make them look extra cute. Well, try not to, because these material combinations tend to cause skin irritation in babies. 

Instead, consider getting clothes that are made using 100% cotton. You could also go for natural fabrics like soy-based azlon and rayon from bamboo. Avoid onesies made using polyester and nylon because they can be uncomfortable and cause irritation because they are not designed to regulate a baby’s temperature or prevent moisture buildup.

3. Functionality 

Newborns don’t need fancy, over-the-top clothes. Always go for comfort over style. You also want to focus on getting onesies that fit your little one well. They should not be too tight or too loose. Whenever you can, make sure the onesie you get has an elastic neckline instead of a fixed one to reduce the risk of strangulation.

4. Season

What’s the weather and climate like as you are shopping for onesies? Always buy season-appropriate clothing when shopping for your little one. When shopping in January, go for designs that are suitable for spring because winter clothes will only get you 2 or 3 months out of them. Consider your location as well: New York City clothes will be different from what your baby would need in Southern California.
