Sleep at 8-10 months – What is happening?

Updated: Aug 10, 2022

There can be a common misconception that suddenly all babies begin sleeping through the night at 6 months. HOWEVER, research suggests otherwise, and studies show there can be a rise in night wakes around 9 months.

But WHY is it happening?

There are many reasons why your baby may wake overnight at this age, but below are a few common big changes that are happening for them:

  • Separation anxiety

  • Dropping their third nap and potentially getting overtired by bedtime – you may need to temporarily shorten their last wake window to help this transition

  • Increasing solid food intake – possibility for reactions or an intolerance to foods leading to digestive discomfort

  • Crawling/pulling to stand/walking – babies can start practicing these new skills in their cots

  • Adjusting to longer periods of wake time in the day - around 2.5 - 4 hours

  • Teething

  • Moving to their own room

  • Feeding more at night, and not as hungry in the day
