Sometimes a baby who seems healthy dies during sleep. This is called sudden infant death syndrome or SIDS.
In most cases, a parent or caregiver places the baby down to sleep and returns later to find the baby has died. It's no one's fault. SIDS can happen even when you do everything right.
Although SIDS is rare, it is one of the most common causes of death in babies between 1 and 12 months of age. Most babies who die of SIDS are between the ages of 2 and 4 months.
Doctors don't know what causes SIDS. It seems to happen more often in premature and low-birth-weight babies. It also is seen more often in babies whose mothers didn't get medical care during the pregnancy and in babies whose mothers smoke. SIDS may also be more likely in babies who were part of a multiple pregnancy (for example, twins or triplets) or whose mothers are younger than 20.
When babies sleep on their bellies, they may not breathe well. Not too long ago, side sleeping was said to be okay. But babies placed on their sides can easily roll onto their bellies and could have trouble breathing.
Researchers are studying the possibility that SIDS may be caused by problems with how well the brain controls breathing, heart rate and rhythm, and temperature during the first few months of life. More research on this is needed.
SIDS has no symptoms or warning signs. Babies who die of SIDS seem healthy before being put to bed. They show no signs of struggle and are often found in the same position as when they were placed in the bed.
SIDS is named the cause of death only when no other cause is found. To find out why a baby died, medical experts review the baby's and parents' medical histories, study the area where the baby died, and do an autopsy.
Doing certain things may help protect a baby from SIDS and/or other deaths related to sleep:1
There is no sure way to prevent SIDS, and no exam or test can predict whether a baby is likely to die of SIDS. Don't rely on breathing (apnea) monitors, special mattresses, or other devices marketed as a way to reduce your baby's risk of SIDS. None of these items have been proved to lower the risk of SIDS. The American Academy of Pediatrics does not advise their use.
Remember, SIDS is rare. Be as safe as you can, but don't let fear keep you from enjoying your baby. Tell your baby's caregivers what you expect them to do. Don't assume that they know what to do to help keep your infant safe during sleep.
Each member of your family may respond to the loss of the baby in a different way. These different ways of coping with the baby's death can strain a marriage and a family. Along with feeling grief, family members may be struggling with feelings of guilt. Support from family, friends, your doctor, and possibly other health professionals is very important for everyone.
