A baby nest is a cozy and secure sleeping space designed for newborns and infants. It typically consists of a cushioned bottom and raised sides that provide a womb-like environment, which helps soothe and comfort babies. Baby nests are often portable, making them a convenient option for parents who want to keep their little ones close by during naps or playtime. They also come in a variety of designs and materials to suit different styles and preferences. However, it is important to note that baby nests should never be used as a substitute for a safe sleep environment, such as a crib or bassinet.
