• For more facts about SIDS, see the SIDS Fact Sheet from the National Institute for Child Health and Human Development.  It also contains a list of SIDS support organizations.

• Put your healthy baby to sleep on his or her back for naps and at night. You can let your baby have awake “tummy time” during the day, when an adult is there to watch the baby. “Tummy time” is important for your baby’s development and also will help prevent positional plagiocephaly or flattened head.
• Babies who are put down on their sides, and then roll onto their bellies are especially at risk.[1]
• Make sure your baby sleeps on a firm surface.
• Do not put soft materials like pillows, comforters, sheepskins or stuffed animals in bed with your baby.
• Make sure your baby’s crib is safe.  Here is a crib safety checklist from the American Academy of Pediatrics.
• When traveling, beware of hotel and motel cribs—many are not safe.
• Don’t let your baby share a bed with sibling [2]
• Don’t use soft or loose bedding2. Blankets should come to baby’s chest and be securely tucked on both sides under the mattress. You can also skip the blankets altogether, and simply dress your baby in warm sleep clothing. Just make sure your baby is not overheated.
• Keep the room temperature comfortable—not too warm, and don’t over-bundle your baby. [3]
• Don’t let anyone smoke around your baby. A recent study showed that nicotine interferes with a brain protein key in breathing.[4]
• If you are pregnant, get early and regular prenatal care, and don’t smoke.[4]
• Breastfeed your baby.  Research is inconclusive (some studies say “yes,” and some say “no”) on whether breastfeeding is a protective factor [3]; however, even if it does not reduce the risk of SIDS, breastfeeding will benefit you and your child in many other ways!  (See Your Child:  Feeding Your Child.)
• Be sure to talk to anyone caring for your baby, such as childcare providers, friends, sitters, or grandparents about the safe sleep practices above.  Research has shown that a large proportion of SIDS deaths occur in childcare settings [5].  When a baby is used to sleeping on their back, and then is put tummy-down to sleep, their risk of SIDS is greater [2].  Consistency is key, and goes for naps as well as nighttime sleep. Because of the higher risk in childcare, the American Academy of Pediatrics has started the Healthy Child Care America Back to Sleep Campaign.

• Healthy babies under six months should sleep on their backs.
• Do not sleep with your baby if you have had drugs or alcohol, are extremely tired, or for any other reason may have reduced awareness of your baby [3] [4] [6].  Even some prescription or over-the-counter medication, such as pain-killers, antihistamines or sleep-aids can reduce your awareness of the baby. 
• Breastfeeding moms tend to be more aware of baby than the co-parent, so put baby between mom and the wall or side rail, until the other parent develops a good nighttime awareness of the baby.  Be sure there are no crevices in which your baby could become trapped.
• Don’t sleep on soft surfaces with your baby—like waterbeds, pillows, comforters, soft mattresses, beanbags, or couches.  Sleeping on a couch with a parent is associated with a higher risk of infant death. [6] 
• Do not use soft, loose bedding [2], such as comforters or quilts [6].  Dress your baby in sleep clothing of similar warmth to what you are comfortable wearing.  Remember that sleeping with other warm bodies will keep your baby warmer.
• Make sure your bed is baby-safe.  It should not have spaces between the mattress and wall, side rail, headboard or footboard, bed frame sides, or other furniture.  Do not use side rails, headboards, or footboards that have slats or cutouts that could entrap the baby’s head.  Mesh insert side rails are safest.
• Obese parents should be extra cautious.
• If you smoke, do not co-sleep with your baby, [7] [8] [9] [10] [11] and never smoke around your baby, or allow anyone else to do so.
• Keep curtains, blinds, and dangling strings well away from the bed and out of baby’s reach.
• Only one baby or child at a time should share the bed with parents.
• Don’t allow other children [2] —not even siblings—or adults other than parents to sleep with the baby.
• Room-sharing with parents was found to lower the risk of SIDS [6] in a British study.  If bed-sharing is not for you, but you want to keep your baby close, consider a crib or co-sleeper in your room or up next to your bed for easy breastfeeding at night.
