SIDS, Sudden Infant Death Syndrome, is a life-altering, grief-filled event.  There are some ways to decrease the risk.

• Infants should be placed on their back to sleep until 12 months of age.  Side sleeping is not suggested.
• Sleep on a firm surface, like a firm mattress covered with a fitted sheet.
• Sharing a room with an infant, without sharing a bed, can reduce the risk of SIDS by up to 50%
• Soft objects (loose bedding, stuffed animals, and pillows) should be kept out of the crib.
• Pregnant women should receive prenatal care
• Avoid smoke exposure during pregnancy and after birth.
• Avoid alcohol and illicit drug use during pregnancy and after birth
• Breastfeeding reduces SIDS risk.
• Do not use home cardio respiratory monitors (like apnea monitors) as a means of reducing the risk of SIDS.
• Offer the infant a pacifier at naptime and bedtime.
• Avoid overheating of infants.

Hope this helps.
