Cradleboards are built with a broad, firm protective frame for the infant's spine. A footrest is located at the bottom of the cradleboard. A cradleboard also has a rounded cover over the infant's head that is similar to a canopy or a modern-day baby carriage hood. The purpose of this headpiece is to provide shade for the infant, since it could be covered with an animal skin, or a blanket in winter to protect against the elements in colder climates. The headpiece also provides extra head protection in case anything bumps against the cradleboard. Ornaments and sacred amulets are often attached to the headpiece as well, for example "beaded umbilical cord cases, and dream catchers or medicine wheels", to amuse and help the infant develop his or her eyesight.
