Dressing a premature baby in properly fitting clothes is important for their health, comfort, and safety.

Clothes that are too big can interfere with medical equipment, bunch up uncomfortably, or fail to keep the baby warm—something preemies struggle with due to low body fat. Well-fitting clothing helps regulate body temperature, protects sensitive skin, and allows for easier care. It also provides emotional comfort for both the baby and parents, helping with bonding during a challenging time.

Now that you have the perfect size – let’s find you the perfect romper!

Our Zippered Romper is thoughtfully designed for preemies and NICU babies, offering soft, breathable bamboo fabric and accurate sizing for a gentle fit.

Convenient features like fold-over mitts, foot cuffs, and side openings for wires make it both practical and comfortable. It’s the perfect blend of functionality and sweetness for your little miracle!
