Cot Death (Sudden Infant Death Syndrome)

Cot death is the sudden and unexpected death of a baby who seems healthy during sleep. It is also called sudden infant death syndrome (SIDS).
It can happen anywhere a baby is sleeping. This includes a cot, pram, bed, car seat or baby seat.
Cot death is one of the main causes of death in babies from 4 weeks to 12 months of age. It is most common between 2 and 4 months of age. It can also happen to older babies.
Because the cause of cot death is not known, it cannot be completely prevented. But research has shown that you can take steps to reduce the risk.
Apnoea or breathing monitors cannot prevent cot death. These monitors alert parents and carers to apnoea (stopped breathing) or an apparent life-threatening event.
Babies who die from cot death cannot be successfully resuscitated. Babies who have an apnoea can be.
Babies who sleep on their tummies have a higher risk of cot death. It is not safe to place your baby on their side because they may roll onto their tummy.
You should always:
Your baby should sleep in a cot in the same room as you for at least the first 6 months.
The risk of cot death is higher for babies who sleep in a separate room.
Bed sharing or co-sleeping in the same bed can be dangerous. It can increase your baby’s risk of suffocation and cot death.
Make sure the cot is in good condition. The mattress should be clean, firm and flat with no tears. It should fit neatly inside the cot. Make sure there are no gaps between the mattress and the edge of the cot where your baby might get trapped.
Keep the cot clear of all objects. Putting objects in the cot can increase your baby’s risk of suffocation.
Objects you should never put in your baby’s cot include:
These objects can suffocate your baby.
Never fall asleep while holding your baby on a sofa, couch, armchair or beanbag. This significantly increases the risk of cot death.
Never leave your baby unsupervised in a sitting device. This includes car seats, baby seats, baby carriers and slings, or similar products. Sleeping in a sitting position can make it more difficult for your baby to breathe.
Overheating can increase your baby’s risk of cot death.
Do not overdress your baby for sleep. A nappy, vest and babygrow are enough. Do not use a hat, unless your GP or midwife tells you to. Use less clothing in warmer weather.
Make sure the room your baby sleeps in has a comfortable temperature – not too warm or too cold. Room temperature should range from 16 to 20 degrees Celsius. Use a room thermometer to check the temperature.
Never place your baby to sleep next to a radiator, heater, fire or in direct sunlight
Your baby’s risk of cot death increases with every cigarette you smoke. The more you or other people smoke in your home, the higher the risk to your baby.
Do not allow anyone to smoke in your home, car or around your baby. When you go out, do not bring your baby into smoky places.
If you or your partner smoke, you should not share a bed with your baby. This greatly increases the risk of cot death. It does not matter where you smoke or if you never smoke in bed.
Smoking during pregnancy increases your baby’s risk of cot death. If you smoke during pregnancy, your baby is more likely to be born prematurely or have a low birth weight.
Babies who are premature and have a low birth weight have a higher risk of cot death.Getting help to quit
Breastfeeding your baby reduces the risk of cot death. Aim to breastfeed your baby for as long as you can.
Some mothers like to breastfeed their baby in bed. It is safe to feed your baby in bed as long as you put them back in their own cot to sleep.
Some research shows using a soother (dummy) at the start of sleep may reduce the risk of cot death.
