What is a "sleepsuit"?

A sleepsuit is a one-piece garment designed for infants to wear during sleep. It is typically made of soft, breathable fabric such as cotton or bamboo and features long sleeves and legs to provide full coverage. The suit usually has a zipper or snap closures down the front, making it easy to put on and take off. Some sleepsuits also come with built-in feet to keep babies' toes warm. Sleepsuits are designed to provide comfort and warmth for infants while they sleep, and can also help to prevent them from scratching their faces or getting tangled in loose blankets during the night.
