Place babies on their backs to sleep, both at nighttime and at nap-time: Research shows that this is the only recommended position for sleep and it is known to reduce the risk of SIDS. Fewer babies die of SIDS when they sleep on their backs.
Place babies on a firm mattress in an approved crib: Do not put babies to sleep on soft mattresses, sofa, sofa cushions, waterbeds, sheepskins, or other soft surfaces.
Remove all fluffy and loose bedding from the sleep area: Make sure you take all pillows, quilts, stuffed toys, and other soft items out of the crib.
Make sure the baby’s head and face stay uncovered during sleep. Keep the baby’s mouth and nose clear of blankets and other coverings during sleep. Use light sleep clothing. If you do use a blanket or another covering, make sure the blanket is light.
Do not smoke around babies. Create a smoke-free environment around babies, with no one smoking near babies. If you must smoke, do so outside.
Do not let babies overheat during sleep. Keep babies comfortable during sleep, but not too warm nor too cold. Babies’ sleeping areas should be at a temperature that is comfortable for adults. Too many layers of clothing or blankets can overheat babies.
