An infant bed (commonly called a cot in British English, and, in American English, a crib, or far less commonly, stock) is a small bed especially for infants and very young children. Infant beds are a historically recent development intended to contain a child capable of standing. The cage-like design of infant beds restricts the child to the bed. Between one and two years of age, children are able to climb out and are moved to a toddler bed to prevent an injurious fall while escaping the bed.
Infant beds are more common in Western countries, employed by the majority of parents as an alternative to sharing a bed (co-sleeping).
