To reduce the risk of SIDS, it is best to put your baby to sleep on their back in a crib, cradle, or bassinet after feeding.
If using an alternative sleep surface, ensure it is firm, flat, and placed on the floor. Examples may include a basket, a box or carton, a washtub, or a drawer on the floor. Keep the surface dry, pest-free, and away from pets. Ensure that nothing can fall on the baby, and that the surface will not be tripped on. The sleep surface needs minimal padding – a light blanket wrapped around and taped to the bottom of a sturdy piece of cardboard can be used as a mattress.
