Co-sleeping, bed-sharing and room-sharing; what you need to know

Co-sleeping, bed-sharing and room-sharing; what you need to know

Are you having separation anxiety at the thought of your baby being out of your sight? Are you worried about the dangers that could befall your bundle of joy during sleep?

Many mums feel unsettled or downright panicky at the thought of their baby sleeping in a different room from them. That’s only natural — your baby has slept with you for the past nine months. By now, it’s a habit.

But before you decide upon your baby’s sleeping arrangements, you should take a closer look at the situation.

Sleep deprivation is a real challenge for new parents. Finding ways for everyone to get a good night’s sleep becomes a top priority. There are three ways of keeping your baby near you when you sleep:

  • Bed-sharing
  • Co-sleeping
  • Room-sharing

Some parents use these terms interchangeably, but co-sleeping and bed-sharing are actually different things.

The NZ Ministry of Health recommends room-sharing for at least the first six months of your baby’s life and ideally for baby’s first year. They do, however, caution against bed-sharing.

Let’s look at the difference between each of these methods and examine the pros and cons of each.

Bed Sharing

Bed-sharing is when your baby sleeps in your bed with you. It can be appealing to parents who can’t bear the thought of being away from their baby. It’s also convenient when you are breastfeeding.

You may be wary of sharing a bed with your baby because recent campaigns have cautioned against it order to avoid Sudden Infant Death Syndrome (SIDS) or a Sudden Unexplained Death in Infancy (SUDI).

Research shows bed-sharing can be safe, especially when that baby is breastfed and when it is practiced intentionally.

There are many reasons parents opt to bed-share, including:

  • Not wanting to leave their baby alone
  • Feeling worried about things like SIDS
  • For some babies, it’s the only way they sleep well
  • For financial considerations when parents can’t afford cots
  • Breastfeeding is easier with baby right there

Bed-Sharing Know-How

Here are a few of the things that can make bed-sharing dangerous for young babies — some of these factors play a part in SUDI / SIDS.

  • The height of the bed, coupled with the lack of railings, makes falling a real possibility, which can be catastrophic for a young baby.
  • Many adults prefer a softer mattress, certainly softer than a cot mattress. Those softer mattresses can cause a baby to sink in and pose a larger suffocation hazard.
  • Most adults generally like to sleep with blankets, and those blankets can easily unknowingly be pulled up over your baby’s head. That can lead to suffocation quickly.

The risk of SIDS is greatest in baby’s first four months of life. If you are worried about SIDS, you may want to wait until the peak risk has passed.

If you’re planning to bed-share, there are a few tips you should follow to keep your baby safe:

  • Bottlefed babies should co-sleep or room-share: Breastfeeding causes physiologic changes that entrain mum and baby sleep, making bed-sharing safer.
  • Partner agreement is essential: Both parents sharing the bed should be on board with having baby there too.
  • Don’t bed-share if you’ve been drinking or you’ve been taking drugs: It’s too risky for your baby. Anytime you’ve had alcohol; your baby should sleep elsewhere
  • Stay away if you’re a heavy sleeper: If you’re a heavy sleeper (or if your partner is), you shouldn’t bed-share. You’ll be less likely to notice any problems that are occurring.
  • If you are obese, it’s better for baby to have a separate sleep space.
  • Don’t bed-share if you or your partner smoke: Even if you don’t smoke in bed, smoking during pregnancy and exposure to second- and third-hand smoke make bed-sharing dangerous for the baby.
  • Dress warmly: Wear a shirt that will keep you toasty, so you don’t have to pull the blankets up any higher than your waist. 
  • Create a safe sleep space: Move your bed away from walls, and perhaps take it off its frame. While that may make you nervous because of the risk of your baby falling from the bed, it’s easy for a baby to suffocate because they get trapped between the wall and the bed. Make sure your mattress is firm and never co-sleep on a waterbed.
  • Never allow an infant to bed-share with siblings: And no siblings or pets in bed with you and baby when you’re bed-sharing


If the thought of bed-sharing makes you nervous, you can opt for another form of sleep sharing. Co-sleeping can refer to a situation where you sleep in your bed and your baby sleeps in a bassinet or cot that attaches to your bed or is right next to your bed. Think of it as a sidecar for your bed.

While the rest of the cot or bassinet has full sides to it, the side that is next to your bed is lowered or off altogether. That allows you to touch or see your baby in the night without having to get out of bed to do so.

Co-sleeping isn’t an ideal solution for everyone, but some parents truly benefit from it.

Here are some of the reasons you might want to consider co-sleeping.

  • You want your baby right next to you but aren’t comfortable with the idea of bed-sharing.
  • You’re breastfeeding your baby and want to be able to do so in the middle of the night with as little disturbance as possible for everyone involved.
  • You have a fussy sleeper on your hands and being next to them seems to soothe your baby.
  • You’re worried about the possibility of SIDS and recognize that room-sharing methods like co-sleeping reduce that risk.
  • You have less anxiety when your baby is in sight.
  • You love to wake up next to your baby in the morning — having that cute little face be the first thing you see is a great feeling.

Because co-sleeping products are still a fairly new market, there aren’t a lot of products to choose from yet. Keep in mind there are no safety standards around co-sleeping products, you should use your judgement to ensure the product you're using is safe (firm mattress that fits well, breathable sides such as slats or mesh and no bumpers).

Safety Check

If you opt for a co-sleeper that has a lowered side, you’ll need to make sure it rests firmly against your mattress, so there is no room for your baby to fall out.


If you’re looking for another safe way to share sleeping space with your baby, you’ll want to consider room-sharing. Room-sharing comes with a host of benefits for babies and parents.

It can:

  • Ease a parent’s anxiety.
  • Save them money because they won’t have to buy a baby monitor.
  • It makes breastfeeding more convenient for both mums and babies.
  • It may help a parent and baby sleep better.
  • It doesn’t carry as much risk with it as bed-sharing and is more time-tested as a method than co-sleeping is.

Room-sharing isn’t for everyone. While some parents find they sleep better with their babies in the room, others don’t fare as well. If you’re an extremely light sleeper, you might find that room-sharing, co-sleeping, or bed-sharing is too distracting to your sleep.

Babies make a surprising number of noises when they sleep, and every one of those sounds might be enough to disrupt your sleep and potentially theirs if you feel the need to check on them in their cot with every noise you hear.

The Bottom Line

It’s natural for you not to want to take your eyes off your baby. Your number one duty is to protect them, and that’s easier to do when you’re in the same room.

Weighing your options and choosing the one that works best for your family is the key to everyone getting a good night’s sleep. Practice safety in any sleep situation to keep your baby safe. Make informed decisions about co-sleeping, if that’s your choice, so you can get the rest you need while keeping your baby safe.
