Cradleboard
Cradleboards have been used in cultures ranging from the sub-Arctic regions of present-day Canada, down to Mexico and Central America. In Arctic regions, cold weather does not make a cradleboard feasible for the infant's survival, and infants are carried in a sling worn under the mother's parka. Cradleboards were widely used by indigenous people across present-day North America. Cradleboards are used by the Kickapoo people in Mexico and were used by Aztecs and the Seri people  and Mayan communities as far south as Belize. In present-day South America, most indigenous cultures used slings or pouches, sometimes called a rebozo,  rather than cradleboards. Cradleboards were used in the southernmost part of the continent, in the Patagonia region.
