Developmental considerations for transitioning between sleep surfaces

Bassinet to cradle/crib: A bassinet may be used until an infant can roll over or it reaches the weight limit as outlined by the manufacturer, whichever comes first.

Cradle to crib: A cradle may be used until an infant has achieved the developmental task of pushing up on its hands and knees when awake or when it reaches the weight limit outlined by the manufacturer, whichever comes first.

Crib to bed: A crib may be used until a child is taller than 90 cm (35 inches) or until a child attempts to climb out of the crib, whichever comes first. Children who are over 90 cm (35 inches) or who have tried to climb out of their crib should be transitioned to a toddler bed or other bed to prevent them from falling over the crib bars and out of the crib. On average, children are about two years of age when they reach 90 cm (35 inches).

Sub-Heading/Title: Home monitors

A systematic review found no evidence that home monitoring may be of use for preventing SIDS among healthy infants.

Some infants may require home cardiorespiratory or oximeter monitoring as prescribed by physicians for the management of special medical conditions. These monitors should be used as prescribed.
