Baby charity the Lullaby Trust advises parents to follow these cot and sleep-safety tips:
1. Keep your baby's cot in your room with you for the first six months.
2. The recommended room temperature for a baby to sleep in is 16-20ºC (61-68ºF) – use a room thermometer to check before putting your baby to bed.
3. To check whether your baby is too hot, look for sweating or feel your baby's tummy or the back of their neck, not their hands or feet.
4. The safest sleeping position for your baby in a cot is lying on their back, not on their front or side (unless your doctor advises otherwise), until your baby is able to roll from back to front and back again.
5. Place your baby with their feet to the foot of the cot, so they can’t wriggle down under the covers. Don’t worry if they wriggle up and get uncovered. Alternatively, you can use a baby sleeping bag instead of bedding.
6. It can be dangerous if your baby’s head gets covered when they're sleeping. To avoid this, tuck in the bedclothes firmly around your child, and no higher than shoulder level.
9. Keep the cot out of direct sunlight.
10. Babies need to lose excess heat from their heads. So if you've been out with your baby and they fall asleep, remove their hat and extra clothing as soon as you come indoors or enter a warm bus, train or shop, even if it means waking your baby.
Watch our video below to learn about four products you should steer clear of. They're listed as baby sleeping bags by the sellers on online marketplaces, but they're not the traditional-style sleeping bags and we'd advise against buying them.
Baby sleep poisitioners, cushioned sleeping pods and baby nests are popular with parents, but we have concerns.
In October 2017, several prominent retailers (including eBay, John Lewis and Tesco) stopped selling these products for babies under six months, citing concerns over safety.
These products do not provide a flat, safe sleeping surface and they pose a risk of suffocation if your baby rolls on to their front. So they should never be used without supervision.
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 or use them.
Which? doesn't review these products, and current safe-sleeping advice from The Lullaby Trust is to keep cots clear of pillows, toys, bumpers and sleep positioners, because the evidence shows that this reduces the risk of sudden infant death syndrome (SIDS).
