Sleep Regressions

There are 5 well-known sleep regressions and these are:

> 4 months > 9 months > 12 months > 18 months > 24 months

The first regression occurs between 4-6 months old and is triggered due to the maturation of the circadian rhythm’s night cycles.

Signs of the 4 month sleep regression include:

  • Increased fussiness

  • Multiple night wakings

  • Reduced naps or “disaster naps”

  • Changes in appetite

The second regression is the 9 month sleep regression which will typically present around 9/10 months. This can be the point of sleep falling apart, even if a child was sleeping well previously. The trigger for this regression is linked to the development of separation anxiety and also the fear of missing out peaks at this age.

Signs of the 9 month sleep regression include:

  • The sleep starting to fall apart, even if the child was sleeping well previously.

  • Naps become harder to achieve, particularly if there was no schedule in place already

  • Night time sleep becomes worse with some babies waking excessively

  • Crying when put to bed

  • Separation anxiety during the awake time

The last three regressions are at 12 months, 18 months and 24 months and all caused by a cognitive development along with a wave of separation anxiety.

Signs of these sleep regressions include:

  • Children crying when put to bed, even if previously a good sleeper

  • Night wake ups

  • Early morning waking

  • Nap refusal/resistance or short naps

There is not much you can do to stop the regressions from occurring. However, it is certainly possible to reduce the impact of each regression and swiftly move through them by following the suggested approaches:

  • Maintain nap schedule and nap durations

  • Put your child to bed confidently

  • Spend lots of quality time during the day with your child to ease the separation anxiety

  • Establish a good wind-down routine, with lots of quality quiet time as part of the wind-down
