• Cradle boards served as a means for carrying
  infants on their mothers backs. Infants were
  also propped up against a tree or wall so infants
  could view their world and keep their interest in
  their surroundings. The cradle board was designed
  to provide security when the mother was not
  carrying the infant.

• Cradle boards are designed differently
  according to the various American Indian tribes.
  Crow cradle boards are designed with beaded
  geometric and floral patterns. The designs are
  beaded on the head board, straps and the bottom
  of the cradle board.
