Best Baby Onesie Brands: Your Ultimate Shopping Guide for Newborns

Newborn onesies, also called baby bodysuits, are essential staples in any infant’s wardrobe. These cozy pieces work well alone or layered. Whether it’s a hot summer day or a chilly winter evening, the best baby onesie brands offer comfort all year round. In this guide, you’ll find a detailed breakdown of the best newborn onesies plus helpful shopping tips.

How Many Newborn Onesies Do You Really Need?

Most parents, especially first-timers, often wonder: how many newborn onesies are necessary? According to Ali El Idrissi, CEO of UpChoose, eight to ten onesies is a solid starting point. This estimate comes from data collected from thousands of families.

However, your specific needs may differ. If you have laundry access at home, you may manage with fewer onesies. Nicole Rattner from Rockets of Awesome notes that parenting styles vary. Some parents use onesies all day, while others save them just for sleep.

Babies grow quickly, often outgrowing tiny clothes within weeks. El Idrissi advises parents not to overstock smaller sizes. Instead, balance quantity with practicality to avoid waste and clutter.

Features to Consider When Shopping for Baby Onesies

When shopping for the best baby onesie brands, look out for key features. Here’s what parents should consider:

Fit

Onesies must fit snugly for baby’s safety. Loose ones may bunch up or cause discomfort. Always follow the brand’s sizing guide.

Material

Choose breathable, soft fabrics such as organic cotton or bamboo. Newborn skin is sensitive. El Idrissi warns against synthetic materials like polyester, which may cause rashes.

Ease of Use

Midnight diaper changes are easier with simple closures. Choose envelope necklines, kimono-style designs, or zip-up onesies for convenience.
