Sudden infant death syndrome

Sudden infant death syndrome, also called SIDS or "crib death," is the sudden death of an infant with no identifiable cause. The death usually occurs during sleep and is the leading cause of death in babies between 2 weeks and 6 months of age. Most deaths occur in children between 2 months and 4 months of age. It is estimated that about 2 or 3 newborns out of every 1,000 die from sudden infant death syndrome.

Factors that increase risk of SIDS include:

• sleeping on stomach
• prematurity
• family history of SIDS
• males with low birth weight
• exposure to cocaine and other drugs before birth
• mother ate poorly during pregnancy
• no medical care before birth
• exposure to cigarette smoke
• teenage mother and
• poor family

Parents and caregivers of infants need to know the correct way to position a baby for sleep. The American Academy of Pediatrics recommends that healthy infants be placed on their back for sleep. Studies in Europe and in America show a decreased number of deaths from sudden infant death syndrome when the back position is used. Research shows a greater incidence of sudden infant death syndrome in babies who sleep on their stomachs.

Do not make any changes in your baby's sleeping patterns before talking with your healthcare provider. The stomach position may be recommended for babies with certain medical problems, such as for severe breathing or spitting-up problems, upper airway disorders, or other medical concerns.

Steps can be taken to minimize the risk of sudden infant death syndrome. Follow these guidelines:

• place infants on their back to sleep
• place infants on a firm mattress
• do not place soft toys, pillows, or bedding in the crib
• learn CPR and monitor high risk infants (this requires special training and equipment)
• breastfeeding may reduce risk of SIDS
• moderate room temperature
• place baby in their crib, not in bed with you
• provide a smoke-free environment

Parents often feel guilty or may even blame each other after the death of an infant. These feelings are normal, even though it was not their fault. Speak to your healthcare provider or clergy to share your grief.
