Choosing baby underwear can be tricky with so many styles to choose from. This easy-to-use 3-piece set features a mix of versatile prints and solids in long-sleeve, front-opening romper styles, making it a great choice for first-time parents preparing for their baby’s arrival. From around 2 months, while your baby is mostly lying down, through the sitting stage, front-opening styles are much easier to change than pull-over styles—a favorite among both new and experienced moms. Made with warm, cozy fabric, this set is perfect for winter and also ideal for the cooler days of early spring and fall. As your baby grows, we recommend stepping up from combination, short, and long underwear to romper-style underwear.

With snaps at the crotch to keep everything securely in place, romper-style baby underwear helps keep your baby’s tummy covered and cozy—even during active play or while being held. No more constantly pulling up a shirt, and the snug fit helps keep the diaper in place while gently helping prevent leaks. Whether your little one is wiggling, kicking, or being cuddled, you can feel confident knowing their tummy stays covered. A must-have for busy babies from around 3 months and a true mom favorite!

Designed for easy changes, day after day. Snap buttons are quick and easy to fasten from both the inside and outside, with two-position adjustment to grow with your baby. The underwear is also designed to help keep seams from directly touching your baby’s delicate skin. During the newborn and infant stage, when babies may need to be changed several times a day, easy-to-handle baby underwear can help make everyday changes a little easier for moms.

Baby’s skin is very sensitive and they tend to sweat a lot. Baby underwear is usually made from nearly 100% cotton, but even 100% cotton comes in different types depending on the knitting method. This item uses “jersey knit” fabric, which is breathable and does not easily trap moisture. As it is double-layered jersey knit, it also provides moderate warmth. It is a soft and fluffy warm fabric, perfect for the cooler fall and winter seasons.

Q: How many newborn underwear pieces do I need?
A: We recommend having 5–6 pieces on hand, including a few extras for laundry.
Q: When should I switch from newborn underwear to a baby bodysuit?
A: Combination underwear is generally best suited for the newborn stage, up to around 3–4 months when your baby develops better head control. As your baby starts rolling over and becoming more active, we recommend switching to romper-style underwear to help keep their tummy covered and prevent the underwear from riding up.
Q: When should I switch between different types of baby underwear?
A: As a general guide, switch to a front-opening romper-style around 2–3 months, then to a pull-over style once your baby has better head control. Around 1 year, when your little one starts walking, you can gradually transition to separates. (These are general guidelines and may vary depending on your baby’s development.)

2 snap buttons at the crotch make diaper changes quick and easy. Wear it on its own in warmer weather, or layer it with a T-shirt, leggings, or pants when it’s cooler.
