Reducing the risk of sudden infant death syndrome SIDS

Reducing the risk of sudden infant death syndrome SIDS

Sudden infant death syndrome (SIDS) is the sudden and unexplainable death of a baby younger than 12 months old. These babies appear to be healthy yet die when they are asleep.

Most SIDS deaths occur when babies are one to four months old. The peak time is two to three months old. SIDS is not common. It happens to fewer than one in 1,000 babies in this country.

A sleep sack is the safest way for your baby to sleep. Your baby's arms can either be in or out of the sleep sack.

You may also use a blanket to swaddle. Stop swaddling your baby at two months old.

To help prevent your baby's head from getting a little flatter on one side or in the back:

  • Give your baby lots of tummy time when she is awake.
  • Each week, switch the direction your baby faces in the crib.

There are things you can do to reduce your baby's risk of SIDS. The American Academy of Pediatrics (AAP) recommends the following:

  • Your baby is safest sleeping on his back. Always place your baby on his back to sleep.
  • Use a firm crib mattress covered with a fitted sheet.
  • Never have your baby sleep on a pillow, sheepskin, fluffy bedding or water bed. Never use a couch, sofa or chair as a place for your baby to sleep.
  • Keep soft, loose bedding and toys out of the crib. Don't place pillows, quilts or stuffed animals in the crib. Don't use bumper pads.
  • Don't let your baby get overheated. Keep the room temperature comfortable for an adult. Dress your baby in light clothing.
  • The safest place for your baby to sleep is in your room in a crib or bassinet (not in the same bed).
    • The AAP recommends sharing a bedroom for at least the first 6 months, or preferably until your baby turns 1.
    • Co-sleeping (sleeping in the same bed with your baby) is not recommended.
    • Don’t let your baby sleep with a sibling.
  • Consider offering your baby a clean, dry pacifier at naptime and bedtime. Don't force your baby to take it. If you are breastfeeding, don't offer the pacifier until breastfeeding is well established. This may be at about one month of age.
  • Don't allow anyone to smoke around your baby.
  • Don't use commercial devices or baby monitors that claim to reduce the risk of SIDS. There is no evidence such products reduce the incidence of SIDS.
    If you use these products, they are OK for listening to your baby when you are in different rooms, but they don't prevent SIDS accidents.

Talk with your baby's health care provider about what is best for your baby if your baby often spits up after eating or has breathing, heart or lung problems.
