Cradleboard
In the southwest United States and northern Mexico, among cultures such as the Hopi and Apache, infants would spend most of their day and night in the cradleboard. When they got older, infants were taken out of it more and more, for up to five times per day. When the infant reaches the age when it can sit up unsupported, it is then gradually weaned from the use of the cradleboard, and spends less time in it. At this time, the infant may use a second, larger cradleboard that replaces the first. By the time the infant is a year old and begins to walk, they are generally finished with cradleboard use.
