Sudden Infant Death Syndrome (SIDS) is the death of an otherwise healthy baby under one year of age, with no identified cause after autopsy. An infant’s sleep environment can impact their risk for death or injury. When the sleep environment is a contributing factor (e.g. such as with suffocation), it is called sudden unexpected death in infancy (SUDI). Babies can be injured if left unsupervised in an unsafe place, or if infant products are not used as intended.

Help prevent Sudden Infant Death Syndrome (SIDS):

  • Place your baby on their back for every sleep.
  • Place your baby to sleep alone in a crib, cradle, or bassinet that meets Health Canada’s safety regulations.
  • Ensure a smoke-free environment for your baby, before and after birth. This means preventing first, second and third-hand smoke exposure.
  • Breastfeed your baby.
  • Ensure the mattress is firm with a tight fitted sheet and no loose bedding, bumper pads, or toys.
  • Keep your baby in the same room with you during the first six months of life.
  • Ensure your baby is not covered in any way.
  • Dress your baby in a fitted one-piece sleeper.
  • Keep the room at a comfortable temperature.
  • Do not swaddle your baby.
