Cradleboards were used during periods when the infant's mother had to travel or otherwise be mobile for work, and needed to protect the infant. The cradleboard could be carried on the mother's back, using support from "tumplines", or "burden straps" that would wrap around her forehead, chest or shoulders; if she carried a pack as well as the cradleboard, the pack strap would go around her chest and the cradleboard strap would go around her forehead. The cradleboard can also be stood up against a large tree or rock if the infant is small, or hung from a pole (as inside an Iroquois longhouse), or even hung from a sturdy tree branch. They were also used when longer travel was required, as the cradleboard could be attached to a horse for transportation.
