A sleep suit is a type of clothing designed for infants and young children to wear while sleeping. It typically features a soft, cozy fabric and is often designed with long sleeves and footed bottoms to keep the child warm and comfortable throughout the night. Sleep suits can come with zippers or snaps for easy dressing and diaper changes. These garments are often used as an alternative to blankets, reducing the risk of suffocation and ensuring a safer sleep environment. Many sleep suits are also made with breathable materials to help regulate the child's body temperature, promoting better sleep quality.
