Baby care 101


  • Always put baby to sleep on her back to avoid SIDS.
  • Respond quickly to your crying baby, but don’t shake her.
  • Give your baby some tummy time when she’s awake.

Sudden infant death syndrome

Sudden infant death syndrome (SIDS) is the unexplained death of a baby under 1 year of age while sleeping. SIDS can happen without warning to a baby who seems healthy.

SIDS is the leading cause of death in babies between 1 month and 1 year old. Most SIDS cases happen in babies between 2 and 4 months old.

SIDS is sometimes called crib death. Cribs don’t cause SIDS, but other sleep issues can increase your baby’s risk for SIDS.

What causes SIDS?
We don’t know what causes SIDS. But some things can put babies at higher risk of SIDS than others, including:

Sleeping

  • Sleeping on his tummy or on his side
  • Sleeping on pillows, soft surfaces or soft bedding
  • Wearing too many clothes to sleep or sleeping in a room that is too hot. These things can cause your baby
  • to overheat. 
  • Co-sleeping. This means that your baby sleeps with you in your bed. Half of all babies who die of SIDS are babies who share a bed, sofa or sofa chair with another person.

Individual characteristics

Can you lower your baby’s risk of SIDS and other sleep-related dangers?
Yes. Use these tips to help keep your baby safe during sleep.

Are there any products that can lower your baby’s risk of SIDS?
No. The American Academy of Pediatrics (AAP) doesn’t recommend using products, like special mattresses or wedges, aimed at reducing the risk of SIDS. There is no evidence that these products reduce the risk of SIDS or suffocation.
