The Department of Health's recommendation is that the safest place for your baby to sleep in the first six months is in a cot in your room. However, although most parents don’t plan to sleep with their baby, around half of all mums in the UK do so at some time in the first few months after birth. Sleeping in the same bed as your baby is called co-sleeping or bed sharing.
Some parents co-sleep with their baby for part of the night or during the day so that they can get more rest. They might breastfeed their baby while they doze or sleep, for instance, or co-sleep because they find it easier to settle their baby this way. Sometimes parents fall asleep accidently or without meaning to. This can be risky, particularly if this happens on a sofa or armchair (see section below).
It’s therefore important that all parents have accurate information about co-sleeping even if they don’t plan to do so, as many parents co-sleep with their baby or fall asleep accidentally.
National co-sleeping guidelines
The National Institute for Health and Care Excellence (NICE) updated its recommendations about co-sleeping in December 2014 and confirmed that although Sudden Infant Death Syndrome (SIDS) is rare, it does happen more often when parents or carers sleep with a baby (on a bed, sofa or chair).
Sudden Infant Death Syndrome or SIDS is the term used to describe the sudden and unexpected death of a baby that remains unexplained after thorough investigation. Other medical terms that can be used are Sudden Unexpected Death in Infancy (SUDI) or Sudden Unexpected Death in Childhood (SUDC), if the baby was over 12 months old.
The NICE guidance doesn't distinguish between co-sleeping on sofas or chairs and bed-sharing although there is evidence that it is more dangerous to fall asleep with a baby on a sofa or chair.
The guidance also confirmed that the link between SIDS and co-sleeping is greater if either parent smokes, and may be greater if parents or carers have been drinking alcohol or taking drugs that affect their awareness.
Premature babies and babies with a low birthweight (less than 2.5kg or 5.5lb) also have a greater chance of SID.
If you co-sleep with your baby, here is some guidance about sleep safety:
- Make sure your baby can’t fall out of the bed or become trapped between the mattress and the wall.
- Keep your baby cool by using sheets and blankets rather than a duvet.
- Ensure bedding does not cover your baby’s face or head.
- Always put your baby to sleep on their back rather than their front or side.
- Babies don’t need a pillow until they are at least a year old. They should also be kept away from parents' pillows.
- Never risk falling asleep with your baby on a sofa or armchair. If you’re feeling really tired and think you may fall asleep with your baby while feeding or cuddling them on a sofa or armchair, move to a bed (keeping in mind the safety guidelines above) or, if possible, ask your partner, friend or family member to look after them while you get some rest.
