I realise co-sleeping at all, never mind extended co-sleeping is something that a lot of people frown upon but I don’t really see why. As the years go by, I am starting to realise more and more keenly that the amount of time I have of being your entire world is so short, and getting shorter by the day.

Co-sleeping is a decision some parents make to allow babies and young children to sleep alongside either one or both parents.

Extended co-sleeping is simply a decision some parents make to carry the practice on as the child becomes a toddler. A lot of people make the choice to extend co-sleeping beyond the baby years, not as part of a long term plan, but as a continuation of normality.

There are pros and cons to extended co-sleeping, which I will discuss, but usually, it happens because parents have gotten used to it, because they like it, and because normalisation simply happens.

Some parents make an early conscious decision regarding extended co-sleeping, both for and against, based on a perception of the benefits or pitfalls. Neither choice is wrong or right; ultimately the choice should be made based on individual circumstances.

Benefits Of Extended Co-Sleeping

We have found there to be a number of benefits to extended co-sleeping with our children. These include;

Better Sleep

Practising co-sleeping can potentially result in both parents and the baby getting more, better quality sleep over time. Comforting your toddler is so much easier when the are within arms reach. Not only that, the toddler is more likely to sleep for longer periods of time if they are in a comfortable safe environment, increasing the chances they will self-soothe if they wake up scared.

Bonding

Extended co-sleeping extends the period of time that parents are bonding with their child through daily experiences. Continuing this bonding experience into the period of their lives when a toddler is becoming more aware of their surroundings and the people withing it makes it more likely they will associate the parents with times when they feel safe, comfortable, and sociable.

Extended co-sleeping has been around for a very long time, and it evolved precisely for this reason. Many people feel this bonding period is an essential part of a child’s life.

Stress

A study has shown that stress levels reduce significantly in mothers and babies who co-sleep. It has been shown that extended co-sleeping helps with balancing the hormone cortisol, resulting in less stress, and facilitates better growth and development of both physical and mental capacities among toddlers.

Continuing co-sleeping into the toddler years can also result in physiological stability; their temperatures, heart rhythm, and breathing are likely to be more stable as a result of sleeping in a shared environment they are comfortable in.

Mental Strength

Studies have shown that extended co-sleeping can improve long-term emotional and mental health. Self-esteem, anxiety, happiness, and behaviour problems can all potentially be positively affected by choosing to practice extended co-sleeping. It can also reduce a child’s fear of sleeping, by simply not removing the child from a familiar environment they are happy in.

Parental routine – simply put, if parents have become used to sharing a bed with their baby, it is far simpler to continue with the arrangement. Changing an established routine can be problematic for both parents and the child, and it is only natural to wish to delay this shock to the system. There is nothing wrong with making a decision on extended co-sleeping for this reason.

Do Co-Sleeping Babies & Children Wake More?

A 2005 study in the USA examined the difference in sleep patterns among children aged 3-15 months old. The study suggested that co-sleeping children had shorter periods of being awake than non-co-sleeping children and that they spent an average of 40% of their time overnight face to face with their mothers. This suggests that the comforting factor is the overall factor in helping co-sleeping children achieve better sleep patterns. 

The arguments for getting more sleep are hard to ignore, as is the benefit of feeling safe and secure as a toddler at the time of day when they feel most vulnerable. The study also found that the majority of Caucasian families choose to practice extended co-sleeping reactively, in response to a sleep problem developing in their children.

This makes a lot of sense. Conversely, African American and Hispanic families tend to choose to do so for cultural reasons. Whether the decision is cultural or reactive, the benefits to sleep can’t be denied.

Is Co-Sleeping Bad For Development?

Whether co-sleeping is bad for development or not is heavily dependent on circumstances and context. There is a natural cross-over point when a bonding experience becomes a dependence issue, but this will be different for each individual and child.

Besides, whether over-dependence at this age is a bad thing or not is debatable, as a dependent toddler will have plenty of time to develop independence as they get older.

Not only that, independence isn’t only related to sleep; a child can gain this through independent play, teaching problem solving, and general all-round positive parenting. 

In some circumstances a co-sleeping child may develop issues around sleep. If the child’s sleep is broken and shorter as a result of them waking up repeatedly due to the movement and nightly noises of their parents or siblings, there is the possibility they may continue this sleep pattern into their later years. This will be dependent on the sleeping patterns of those they share their sleeping space with.

Another development issue may arise whereby the infant will develop a complex whereby they struggle to sleep alone in their later childhood years. Again, this will be specific to each child, and it is impossible to predict who would be impacted on by this and who wouldn’t. 

There have been some fears raised by epidemiologists and infant health experts around co-sleeping and infant fatalities. While these can’t be dismissed out of hand, it is worth noting that these studies don’t allow for other circumstances.

For example, parental substance use, bed-sharing arrangements, and the position of the sleeping child are not taken into account. Maintaining a safe approach to co-sleeping, by keeping distance between the parents and child, not placing the toddler in an uncomfortable or stressful position, and constantly reacting to potential hazards should help to prevent this. 

An often-overlooked potential pitfall in development concerns the parents and family unit as a whole. One of the most important aspects of co-sleeping, and extended co-sleeping in particular, is to ensure it is the right thing to do for all involved. If one part of a partnership is unhappy with the arrangement this can foster resentment, result in lost sleep for them and potentially all involved.

In this instance, there is a high likelihood the child will notice the bad feeling, increasing their own feelings of anxiety and reduce their sleep. The best solution to this, as with other aspects of parenthood, is to have an open and honest discussion about co-sleeping. If one parent is set against the idea, this must be addressed as early as possible, to reduce the risk of bad feelings transmitting to the child and impacting on their emotional development.

There is a good chance that the child will let the parent or parents know when co-sleeping is no longer the right approach for them. Children develop very quickly, and they interact with other toddlers and children ad playgroups and pre-schools. If they become aware that their friends all sleep on their own, they will probably want to do the same as a result of their association with other groups of children.

If this is the case, it is worth noting that what is right and wrong for other children is not necessarily right for every child. Most children are capable of putting on a brave face, and it must be acknowledged that while they may want to sleep alone, the reality might put them off after a short while.
