Answer:
keep cribs as bare as possible, don't overheat your baby, Have your baby sleep in in your room, Breast-feed your baby, if possible
Step-by-step explanation:
use firm mattress and avoid placing your baby on thick, fluffy padding, such as lambskin or a thick quilt. Don't leave pillows, fluffy toys or stuffed animals in the crib. These can interfere with breathing if your baby's face presses against them.
sleep sack or other sleep clothing that doesn't require additional covers. Don't cover your baby's head
Ideally, your baby should sleep in your room with you, but alone in a crib, bassinet or other structure designed for infants, for at least six months, and, if possible, up to a year. Adult beds aren't safe for infants. A baby can become trapped and suffocate between the headboard slats, the space between the mattress and the bed frame, or the space between the mattress and the wall. A baby can also suffocate if a sleeping parent accidentally rolls over and covers the baby's nose and mouth
Breast-feeding for at least six months lowers the risk of SIDS.
