Cradleboards are used for the first few months of an infant's life. At that time, babies are carried around a lot, and a portable baby-carrier is a great help. Some cradleboards are woven, as with the Apache. Woven cradleboards are made of willow, dogwood, tule, or cattail fibres. Wooden cradleboards are made by the Iroquois and Penobscot. Navajo cradleboards are made with a Ponderosa pine frame with buckskin laces looped through the frame.
