Revised American Academy of Pediatrics' (AAP) guidelines, released in October 2005, recommend the following:

Always put a baby to sleep on its back. (This includes naps.) DO NOT put a baby to sleep on its stomach. Side sleeping is unstable and should also be avoided. Allowing the baby to roll around on its tummy while awake can prevent a flat spot (due to sleeping in one position) from forming on the back of the head. 

Only put babies to sleep in a crib. NEVER allow the baby to sleep in bed with other children or adults, and do NOT put them to sleep on surfaces other than cribs, like a sofa.

Let babies sleep in the same room (NOT the same bed) as parents. If possible, babies cribs should be placed in the parents' bedroom to allow for night-time feeding.

Avoid soft bedding materials. Babies should be placed on a firm, tight-fitting crib mattress with no comforter. Use a light sheet to cover the baby. Do not use pillows, comforters, or quilts.

Make sure the room temperature is not too hot. The room temperature should be comfortable for a lightly-clothed adult. A baby should not be hot to the touch.

Let the baby sleep with a pacifier. Pacifiers at naptime and bedtime can reduce the risk of SIDS. Doctors think that a pacifier might allow the airway to open more, or prevent the baby from falling into a deep sleep. A baby that wakes up more easily may automatically move out of a dangerous position. However, do not force the infant to use a pacifier. Although pacifier use has been associated with dental problems and breast-feeding difficulties, researchers say the potential benefit (decreased SIDS risk) outweighs the risks. The AAP says that one SIDS death could be prevented for every 2,733 babies who suck on a pacifier during sleep.

Do not use breathing monitors or products marketed as ways to reduce SIDS. In the past, home apnea (breathing) monitors were recommended for families with a history of the condition.  But research found that they had no effect, and the use of home monitors has largely stopped.

Other recommendations from SIDS experts:

• Keep your baby in a smoke-free environment.
• Breastfeed your baby, if possible -- breastfeeding reduces some upper respiratory infections that may influence the development of SIDS.
• NEVER give honey to a child less than 1 year old -- honey in very young children may cause infant botulism, which may be associated with SIDS.

Until the nature of the disease is fully understood, complete prevention will not be a reality.
