18-Month Sleep Regression

This regression occurs because your baby is more autonomous and secure in their physical abilities. They want to engage with their surroundings all the time.

At 18 months your baby will have transitioned to only one nap per day. Night awakenings at this stage are caused by the extra-long wake window between naptime and bedtime.

This regression occurs because:

  1. Your baby is more autonomous and secure in their physical abilities.
  2. They want to engage with their surroundings all the time. But they’re still feeling that separation anxiety. 

Then, an important cognitive milestone happens. They discover how to say “No”. Your little one will start challenging your authority and routines. They may even start with tantrums, a sure sign that the “terrible twos” are coming.

Tips to handle this regression

  • Keep to your routine and schedule, especially at nighttime.
  • Maintain regular nap times
  • Create clear and respectful limits at home
  • Avoid introducing new sleep props.
