Baby Onesies
If there’s one item every new parent buys too few of, it’s baby onesies. Spit-ups, blowouts, and diaper leaks have a way of going through three onesies before 9am — and suddenly that six-pack you bought feels like it lasted about a week. Getting the right onesies from the start means having enough, in the right sizes, from brands that actually hold up through daily washing without shrinking, fading, or losing their snap closures.
We reviewed the 10 best baby onesies and bodysuits on Amazon in 2026 — from Gerber’s legendary 8-pack unisex onesie with 42,000+ reviews, to Carter’s boys and girls print packs, Sleep ‘N Play footies that cover everything from neck to toes, and a romper-style option for outings and photos. Whether you’re stocking up for your own newborn or shopping for a baby shower, the right choice is on this list.
Here’s everything you need to build a baby wardrobe that actually lasts through the first year.

Frequently Asked Questions
How many onesies does a newborn actually need?
Most paediatric experts and experienced parents recommend having at least 10–14 onesies in newborn and 0–3 month sizes. Newborns can go through 3–5 onesies in a single day during the first weeks. Buying an 8-pack like the Gerber Unisex (#1) and a 5-pack like the Gerber Solid (#2) gives you 13 onesies in matching sizes — enough for a full week between laundry cycles.
Should I size up when buying baby onesies?
Yes — most experienced parents recommend buying one size up, especially for the newborn size. Babies grow extremely quickly in the first months, and a newborn-sized onesie may only fit for 2–4 weeks. The 0–3 month size typically fits longer and provides better value. Gerber onesies in particular can run slightly small, so sizing up is a commonly recommended practice across the reviews on this list.
What is the difference between a onesie and a bodysuit?
They are the same garment — “onesie” is a brand name owned by Gerber that has become a generic term in common usage. A bodysuit or onesie is a short or long-sleeve top that snaps closed at the crotch to keep it tucked in and provide diaper coverage. The terms are used interchangeably throughout this list and in everyday baby clothing shopping.
Are Gerber or Carter’s onesies better?
Both are excellent and both have tens of thousands of reviews confirming consistent quality. Gerber onesies tend to be slightly softer straight out of the bag and offer better value per piece in larger packs. Carter’s (Simple Joys by Carter’s) onesies typically offer better print quality and more attractive designs. For maximum quantity at the best price, Gerber is the choice. For better-looking patterns and brand prestige, Carter’s is the choice. Many parents use both — Gerber for everyday rotation and Carter’s for photos and outings.
Should I wash onesies before first use?
Yes — paediatricians universally recommend washing all new baby clothing before first use to remove manufacturing residues, dyes, and any allergens from packaging or transport. Wash with a fragrance-free, dye-free baby detergent. All products on this list are machine washable and safe to tumble dry on low heat.
What is a Sleep ‘N Play footie and when should I use it?
A Sleep ‘N Play footie is a full-coverage one-piece garment that covers the baby from neck to toes, including the feet. It eliminates the need for separate socks, which newborns kick off constantly. Footies are appropriate for both sleeping and daytime wear, and the front zip or snap closure makes nighttime diaper changes significantly easier without fully undressing the baby. The Gerber Sleep ‘N Play footies (#5 and #9) are the footie options on this list.
