Safer sleep for twins and multiples: frequently asked questions

Yes, newborn twins can sleep in the same cot. Research suggests that putting twins in the same cot (co-bedding) can help them regulate their body temperatures and sleep cycles, and soothe each other too. Many parents choose to co-bed their twins because they have limited space and can only fit one cot in their bedroom, but want to follow the safer sleep advice of sleeping in the same room as their babies for the first six months.

If you decide to co-bed your twins in the early weeks and months, there are a few key points to consider:

• Only place them side-by-side in a cot in the early weeks. Make sure they’re not close enough to touch and potentially block each other’s breathing.
• Once any of your babies start to roll, move them to their own sleep space so they can’t roll onto each other.
• If you have triplets or quads, they could share a cot in the early days if they sleep with their feet to the sides of the cot.
• Don’t use rolled up towels, pillows or anything else between their heads as these could wind up blocking their breathing. We also don’t recommend cot dividers.
• Don’t place your babies in the same Moses basket. Moses baskets are too small to share and could lead to overheating.

Bedsharing, also known as co-sleeping, is where babies share a bed or other sleep space with an adult. This is different to “co-bedding” which is where your babies share a sleep space, but not with an adult.

The safest place for a baby to sleep is in their own clear, flat, separate sleep space, such as a cot or Moses basket. However, some parents choose to bedshare and others sometimes fall asleep with their baby without meaning to, so it’s always a good idea to make your bed safer just in case. If you choose to bedshare with twins or multiples, we advise only bedsharing with one baby at a time to reduce the risk of accidents.  

There are certain situations where you should avoid bedsharing completely as there is a higher risk of sindrome della morte improvvisa del lattante (SIDS). In particular, if your baby was born prematurely or had a low birth-weight, which is common in multiples. 

Premature or low birth-weight twins and multiples are often slept close together on the Neonatal Intensive Care Unit (NICU). This is to mimic how they were in the womb (known as the intrauterine environment) and support the development of their vital functions such as their heart rate and breathing.

Once your babies are discharged from hospital, they should be ready to sleep in line with the safer sleep advice for twins and multiples above, which is continued in further detail on our safer sleep pages.

We often promote co-bedding your twins or multiples so that you can share a room with them if you have limited space. Sharing a room with your babies is important for at least the first six months. This is because it lowers the risk of sudden infant death syndrome (SIDS) and means you can keep an eye on them.

There are other reasons you might want to co-bed your twins as well. Research suggests that putting twins in the same cot can help them regulate their body temperatures and sleep cycles, and can soothe each other too.

Once one baby can roll and move around in the cot, it’s time to give them their own separate sleep spaces to keep them safe. This is to prevent them from accidentally blocking each others’ airways (ability to breathe), or overheating.

Babies will need separate sleep spaces once one of them begins to roll or move about the cot. This is because there is a risk they could roll onto each other which means they could accidentally block each others airways (ability to breathe), or risk overheating, which increases the risk of sindrome della morte improvvisa del lattante (SIDS).

It can sometimes be tough to stick to all of the safer sleep advice for practical reasons, especially if you’re short on space.

If you can’t fit two cots in your bedroom, make the advice work for you. You could leave doors open between your room and theirs, or perhaps take it in turns with a partner to sleep with the twins in a nursery room. You might even be able to borrow something smaller than a second cot, such as a crib, for a couple of months.
