Baby Onesies Parents Trust Most According To Real Reviews

A baby onesie is a body suit designed to cover a baby's torso and make diaper changes a breeze. Also known as baby bodysuits, creepers, or snap-gusset shirts, all of these outfits share a common feature: handy snaps or zippers at the bottom, so dressing and undressing your baby is quick and simple.

Thanks to their convenience, onesies are a favourite for both baby boys and baby girls. They're also easy to wash at home and can be worn alone or layered with other clothes, making them a versatile addition to any baby's wardrobe.

Why parents rely on baby onesies

Parents rely on baby onesies for a variety of reasons, including:

• The ease of diaper changes due to gusset snaps.

• Keeping the baby's tummy covered and warm, preventing shirts from riding up.

• Providing a smooth layer under other clothing or serving as a standalone outfit.

• Simplifying dressing, especially for wiggly newborns.

• Helping to contain diaper blowouts, thus protecting the outer layers of clothing.

Different types of baby onesies

Here's a guide to some of the most common types of baby onesies, and when each style might be just right for your little one.

• Short-sleeve onesies: These are short-sleeve bodysuits ideal for warm weather or layering. They are often available in versatile colours like white for easy mixing and matching.

• Long-sleeve onesies: These are sleeved styles that provide warmth in cooler temperatures.

• Footed onesies: These combine a onesie with pants and built-in feet for full coverage and warmth.

• Kimono/wrap-style onesies: These fasten at the side, avoiding the need to pull over the head (good for newborns and umbilical cords).

• Tank top/sleeveless onesies: These bodysuits are designed for very hot weather or as a base layer.

Choosing the right onesie: Materials, features and fit

While most onesies share a common purpose, they differ in materials, features, and fit.

Here are some things to note about each, and how these factors should influence your decision when choosing a onesie.

Materials

Dr. Jennifer Gordon, a board-certified dermatologist, recommends that parents pay attention to the fabric when choosing onesies for their babies.

"Cotton or bamboo are usually good choices," she explains. "They are natural fabrics and usually hypoallergenic. Some cotton blends (typically with spandex or polyester) can offer other benefits such as stretch for mobility, but these synthetic fibres can sometimes be irritating or not as breathable."

Closures

Closures are another important feature to consider when choosing onesies for your baby. Most onesies use snaps, while others use zippers. However, be sure to look for onesies with zipper guards to protect your baby's skin from getting pinched.

Necklines

Just like snaps and zippers, the type of neckline on a onesie makes a difference. Envelope necklines are a great choice for parents who want to make changing quick and easy, while classic crew necks offer a simple, timeless style.

Fit and sizing

Keep in mind that different brands can have different fits and sizes. To make sure your baby's onesie fits just right, it's better to choose based on their height and weight rather than just their age.

Onesies real parents love

1. Carter's 4-Pack Long Sleeve Bodysuits

Alexia McKay, a mom of two girls and the founder of the Dear Black Mommy blogger blog, recommends this affordable four-pack of onesies as a must-have.

"These are great for lounging or bedtime, especially paired with some cozy socks," she says.

McKay also suggests picking up this eight-pack of short-sleeve Gerber onesies, saying, "They are good for bedtime, lounging around, and handling those inevitable spit-ups!"

These versatile onesies come in ten different colours and fit babies up to 12 months old. Made from 100 percent cotton, they feature a comfy crewneck and a convenient snap at the bottom. They are also nicely priced under $25.

3. ergoPouch Sleep Onesie

If you're searching for the ideal bedtime onesie, Lily Walla, a Brooklyn-based toddler mom and the founder and CEO of Auggie, highly recommends this state-of-the-art product from ergoPouch. What sets it apart is its unique TOG rating system, which helps you choose the right thickness for your baby's comfort based on the room temperature.

"I recently discovered this brand and I’m now obsessed with their TOG rating system," explains Wall. "It tells you exactly what your baby should wear based on the room temperature, taking out all the guesswork."

4. H&M 5-Pack Cotton Bodysuits

Jessica Nilson, mom of two boys and creator of the blog CurrentlyJess.com, shares, "I’ve always loved H&M onesies for both of my boys. They come in soft, neutral multipacks that go with everything and layer easily under other outfits. The quality holds up well in the wash, and the price is perfect for how quickly babies grow. They’ve been my go-to for everyday wear during the first year."

5. Magnetic Me

Giselle Mays, a Latina content creator and mother of two, also recommends these onesies, which feature magnetic closures for easy changing.

"I’ve been using Magnetic Me since my first baby, and now it’s a staple in our home,"  Mays explains, "The magnetic closures make changing a breeze, and the quality holds up so well—it’s one of the few things I can actually pass down from baby to baby."

Babies are known for frequent spit-ups and diaper leaks, so it's a good idea to keep a generous supply of onesies on hand. Having about 8 to 12 onesies ensures you won't run out between laundry days.

As your baby grows older, you might find that 6 to 10 per size is enough, since you'll likely need to change outfits a bit less often. Just in mind, however, that babies grow quickly, so try not overstock the smaller sizes.

Tips for dressing baby in a onesie

Dressing your baby in a onesie can be simple. Follow these tips for success:

• Use the envelope neckline to pull the onesie down rather than up over your baby's head. This is especially helpful if there has been a diaper leak or spit-up.

• Snap the gusset from the bottom up. This helps keep the fabric aligned and makes fastening easier.

• Gather the onesie before putting it over the head or feet. This makes it easier to avoid getting stuck or tangled.

• Distract a fussy baby during dressing by using a toy, singing a song, or playing peek-a-boo.

Caring for your baby's onesies

Caring for your baby's onesie is simple when you follow a few steps. Gordon recommends always checking the garment's care label and choosing a mild, baby-friendly detergent.

"You should use detergents that are free of fragrance and dyes," she advises. "Look for 'hypoallergenic' on the packaging. Also, avoid fabric softeners and dryer sheets."

When it comes to common stains like spit-up or diaper leaks, gently treat the area with a little stain remover or soak the fabric before washing. To help the onesie last longer, wash it in cold water to prevent shrinking and fading. Finally, air drying is ideal, but if you use a dryer, choose a low-heat setting to keep the fabric and snaps in great shape.

Safety tips for baby onesies

When choosing baby onesies, it's important to prioritize safety and comfort alongside cute designs. Before making a purchase, check that all snaps and zippers are securely fastened, free of loose threads, and won't irritate your baby's skin.

Additionally, avoid onesies decorated with small, detachable items like buttons, bows, beads, or sequins, as these can be choking hazards. It's also best to steer clear of onesies with drawstrings around the neck or waist, since these can increase the risk of choking, strangulation, or entanglement.

The bottom line

Onesies are truly a must-have for every baby. They're not only comfortable and easy to mix and match with others, but they also make diaper changes a cinch, making them both practical and versatile for everyday use.

When choosing onesies for your child, consider materials, closures, necklines, fit, and sizing to ensure comfort and convenience. It's also a good idea to stock up on several onesies, but try not to buy too many in one size since babies tend to outgrow them faster than you might expect.
