What is SIDS?

SIDS, short for Sudden Infant Death Syndrome, is a mysterious phenomenon in which a healthy baby will suddenly, unexpectedly pass in their sleep. Though scary, SIDS is rare – about 1 in 1,000 – and there are ways to reduce the risk of SIDS:

How Do I Prevent SIDS in My Baby?

Back Sleeping: Sleeping flat on their back on a firm mattress helps prevent SIDS in babies.

Tip: If your baby rolls onto their stomach in their sleep and they cannot roll over both ways while awake, go in and gently turn them over to place them back on their back.

Avoid Overheating: Overheating is shown to increase a baby’s SIDS risk. To keep your baby safe while they sleep, dress them only in one more layer than you’re wearing. Also, keep their room between 68-72° F.

Firm Mattress: Keep your baby safe at night by placing them on a flat, firm mattress with a well fitted sheet.

Bare Bed: Your baby’s bed should be clear of sheets, blankets, toys, pillows, bumpers and anything else except for a well fitted sheet – and your baby, of course!

Breast Feed When Possible: Not every parent can breastfeed, but if you are able to, breastfeeding is shown to reduce SIDS risk in babies.

Room Share: Room sharing may reduce SIDS risk by up to 50%.

No Bed-Sharing: We can’t reiterate enough that bed sharing is dangerous for your baby, your baby should always be in their own, safe sleeping space and not in your bed.

Skin-to-Skin Contact: Studies show that holding your baby against your skin can reduce SIDS risk. Plus, it’s a great bonding experience in general.

Pacifiers: Pacifiers can also reduce your baby’s risk of SIDS.

Don’t Rely on a Baby Monitor: While many modern baby monitors claim to monitor breathing and of course can alert you if your baby is crying, there is not a monitor that can alert you of SIDS or prevent SIDS.
