Where your baby should sleep

The safest place for your baby to sleep is in a cot in the same room as you. Their risk of cot death is lower than babies who sleep in a separate room.

Keep your baby's cot in the same room as you for at least the first 6 months.

Cot safety

Make sure the cot is in good condition and correctly assembled. The mattress should be clean, firm, flat with no tears and fit the cot. An uneven mattress could allow your baby to roll onto their side and stomach. There is a risk your baby could get trapped in a gap between the mattress and the edge of the cot if the mattress doesn't fit properly. This could lead to suffocation.

No pillows or sleep positioners

Do not use sleep positioners and other similar products. They do not prevent cot death or flathead (plagiocephaly) and are a suffocation risk.

Pillows and cushions should not be in the cot as they could suffocate your baby. Do not use them to elevate your baby's head during sleep. This does not reduce reflux and is not recommended.

Keep the cot clear of all objects

Do not have any soft objects and anything loose or fluffy in your baby's cot. This includes cot bumpers, comforters, duvets, toys, teddies, wedges and bedding rolls. These could suffocate or smother your baby.

Dangers to avoid

Sharing a bed with your baby (co-sleeping)

A separate cot in your room is the safest place for your baby to sleep.

Bed sharing or co-sleeping in the same bed can be dangerous. It can increase your baby’s risk of suffocation.

Suffocation can happen when your baby:

  • slips under the bed covers
  • rolls under an adult
  • gets trapped between the bed and the wall
  • falls out of the bed

Your baby should not share a bed with your other children.

Do not share a bed with your baby if you or your partner:

  • are smokers
  • have taken alcohol, drugs (legal or illegal) or medication that may make you drowsy
  • are over tired

You should not bed-share if your baby:

  • is less than 3 months old
  • was premature (born before 37 weeks)
  • had a low birth weight - less than 2.5kg (kilograms) or 5.5lbs (pounds)

Sitting and carrying devices

Cot death does not only happen in a cot. It may happen in a pram, bed, car seat, baby seat or anywhere a baby is sleeping.

Sleeping in a sitting position can make it difficult for your baby to breathe.

Never leave your baby unsupervised in a sitting device. This includes a car seat, baby seat, sling, carrier or similar products. These sitting and carrying devices are not recommended for routine sleep in the home.

If your baby falls asleep in a sitting position, they should be placed on their back to sleep as soon as possible

Sofa, armchairs and furniture

Never fall asleep while holding your baby on a sofa, couch, armchair or beanbag.
