Types of Co-Sleeping

When it comes to co-sleeping there are two different methods: bed sharing or room sharing. Each one has their own benefits and drawbacks. The best one is the one that works for your family. You may even decide to switch between the two styles as your baby grows.

Bed Sharing

This involves having baby sleeping in your bed, either on mom’s side or in between parents. Having baby sleep in your bed has a lot of advantages.

Benefits of Bed Sharing

  • Save money – You don’t need to spend money investing in a crib, or dealing with the hassle of building it up.
  • Keep cozy – When you baby wakes you simply open your eyes and you are there. No more getting up to the sound of your baby screeching down a baby monitor from your warm and snug bed.
  • Instinct – Humans have evolved to sleep with their newborn babies to protect them. It’s natural for parent to lie of their sides in a protective c shape around there baby. Higher rates of sleep arousal mean we have evolved to naturally wake and check that baby is ok.
  • Better sleep pattern – Your baby is more likely to follow your sleep patterns if you bed share. This helps you quickly get through those sleep deprived nights.

Concerns of Bed Sharing

The biggest concern with bed sharing is safety and babies’ risk of suffocation. It’s not simply a case of placing baby in your bed and off you go. Modern day adult beds and sleeping arrangements are not exactly baby friendly. Most parents, especially dads, worry about rolling on top of baby.  If you are in a deep sleep you can roll of top of baby. This is extremely rare and unlikely if you follow safe co-sleeping guidance, which we will discuss later.

Room Sharing

An alternative to sharing your bed with baby is to have them sleep in your room but in their own bed space. The type of bed can vary between a bassinet, crib or co sleeper which attaches to your bed.

Benefits is Room Sharing

  • Great middle ground – Room sharing is a great way to get the benefits of co-sleeping without the disadvantages of discomfort or concerns of rolling onto baby.
  • Tend to baby – Having baby close means you can feed them or change a nappy quickly during the night. Plus if you have an explosive diaper or leaky nappy then it’s only in baby’s area and not yours.
  • Baby adapts – When it comes to moving baby into their own bed room sharing can make this easier. The closeness of room sharing lets baby know you are there but gives them the freedom of their own space.

Drawback of Room Sharing

The main disadvantage of room sharing is that it’s not close enough for some parents. You may prefer to have baby as close as possible and enjoy the skin to skin contact it give you. If you prefer to follow and attachment parenting model, then you’ll probably opt for bed sharing over room sharing. Intimacy is another concern for parents who are considering room sharing.

This is a little area of padding which ‘nests’ your baby. It makes co sleeping easier whether baby is sleeping to the side or in between parents. Baby has its own little sleep area, which makes it less likely parent will roll onto them. They can also be used as a portable sleep area. Using a nest is great for new-borns and can even be used for padding as baby learned to sit upright.

Bed Guard

For older babies opt for a bed guard. You can buy a pillow shaped guard which should cover a good length of your bed. Some parents like to use the mesh toddler bed guards so baby can still breathe should they roll into it. Never use a bed guard for a newborn or baby unable to roll as they can become trapped and at greater risk of suffocation.

For Room Sharers


This is like a little mini crib for baby. As bassinet is a great way for babies to have their own sleep space in your room. Position it right next to you bed so you have easy access if baby should cry during the night. Modern bassinets have supportive mesh sides to allow breathing is they roll over. These also help you to see baby easily when you are lying in bed.

Co Sleeper Crib

These cribs attach to your bed with no side barrier, giving you instant access to baby. They are a great way to get the closeness of bed sharing without the safety risk.  No need to even sit up to tend to baby. They are fantastic for breastfeeding, whilst giving baby their own safe area to sleep.

Benefits of Cosleeping With a Newborn

Whether you chose to co-sleep by bed sharing or room sharing there are some shared benefits between the two methods.

Easier night feeds

Co-sleeping makes breastfeeding so much easier. You don’t need to get up and settle in another room. Simply let baby settle in bed with you and feed whilst side lying. You usually only need to be awake to attach baby and then you can snooze throughout a feed.  This method of night feeds encourages longer breastfeeding relationships.

Reduced Risk of SIDS

Babies who sleep alone are 4 times more at risk of SIDS than babies who co-sleep. Countries where co-sleeping is the norm have the lowest rates if SIDS. A slight increase in carbon dioxide from parent breath stimulates baby to breathe more. Co sleeping babies also tend to sleep more on their back or sides which is a big factor in preventing SIDS.

Babies Cry Less

Co sleeping causes baby to startle less during the night. Startling can cause a baby to cry, so babies who sleep alone cry up to 4 minutes more than a co sleeping baby. Your baby will cry less because you are able to respond to their needs quicker when you are co-sleeping.

Parents get more sleep

With reduced crying and easier night feeds, co-sleeping leads to minimal disruptions during the night. Compare this to solo sleeping where you need to constantly get up to tend to baby in another room. A baby monitor may also cause more disruption to your partners sleep than if baby was in the room with you.

Improved Health

Co sleeping babies are known to have better breathing rates, heart rates and maintain their temperature better. The feeling of security the closeness give them reduce their stress levels. Babies who experience less stress have better emotional and brain development in later life.

Most parents are exhausted from sudden changes to their sleep patterns. Conditions such as anemia, pain or thyroid disorders can all increase your levels of fatigue. This makes you less responsive to baby and unaware of their presence. Try to get as much sleep during the day as possible to avoid this.

Sleep Disorders

Avoid bed sharing if you suffer from a sleep disorder which can make you unresponsive. Conditions such a sleep apnoea, narcolepsy or sleep paralysis will all make you unable to respond to baby should they be distressed. Room sharing is still great option and may be advisable so you partner can tend to baby if you are unable to.


Never sleep with your baby on an arm chair or sofa. When co-sleeping this is the most dangerous place to sleep. This is mostly due to parent being excessively tired and unintentionally co-sleeping. Babies can become easily wedged between the arms and the parent and become trapped or suffocate.

Low Birth Weight or Premature

If your baby was born before 37 weeks or weighted under 2.5kg then you should not bed share. Premature and low birth weight babies are at greater risk of SIDS. Although unknown it is thought that their immature development makes them unable to cope with a bed sharing environment. These babies do greatly benefit from co-sleeping by room sharing.


If you are morbidly obese it is recommend that you room share rather than bed share. You may struggle to recognize when baby is too close to you which put baby at great risk of suffocation. If your partner is extremely obese you should position baby at your side only and not between parents.
