The Lullaby Trust advises parents to follow these cot and sleep safety tips:

  • Keep your baby's cot in your room with you for the first six months.

  • The recommended room temperature for a baby to sleep in is 16-20ºC (61-68ºF) – use a room thermometer to check the temperature before putting your baby to bed. 

  • To check whether your baby is too hot, look for sweating or feel the back of your baby’s neck or his or her tummy, not hands or feet.

  • The safest position for your baby to sleep in a cot is on his or her back, not front or side (unless your doctor advises otherwise), until your baby is able to roll from back to front and back again.
  • Place your baby with feet to the foot of the cot, so he or she can’t wriggle down under the covers. Don’t worry if he or she wriggles up and gets uncovered. Alternatively, you can use a baby sleeping bag instead of bedding.
  • It can be dangerous if your baby’s head gets covered when he or she sleeps. To avoid this, tuck in the bedclothes firmly around your child and no higher than his or her shoulders.
  • Never use a pillow, quilt or duvet if your baby is under one year old. Instead, use cotton sheets or lightweight blankets. 
  • Make sure the mattress is firm, dry and clean – read our guide to cot mattresses for more information.

  • Babies need to lose excess heat from their heads, so remove hats and extra clothing from a sleeping baby as soon as you come indoors or enter a warm bus, train or shop, even if it means waking your baby.
  • Keep the cot out of direct sunlight.

Some research has shown that using a dummy every time you settle your baby to sleep can reduce the risk of cot death.

Baby sleep positioners

In October 2017, several prominent retailers (Mothercare, Tesco, John Lewis and eBay) stopped selling baby sleep positioners for babies under six months, citing concerns over safety. These products pose a risk of suffocation if the baby rolls onto its front, and there have been 12 infant deaths in the US between 1997 and 2010 due to this. The Food and Drug Administration (FDA) in the US released a statement warning about these items, which are also known as 'anti-roll' products, warning parents not to buy them or use them.

Which? doesn't review these products and current safe sleeping advice from The Lullaby Trust is that cots should be kept clear of pillows, toys, bumpers and sleep positioners, because the evidence shows that this reduces the risk of sudden infant death syndrome (SIDS).
