Quick Answer

The 2 to 1 nap transition often causes sleep disruptions because your baby isn't fully ready for one nap, but two naps no longer fit the day. This in-between stage can lead to overtiredness and unsettled nights, but it can be managed with the right structure.

Why this is happening

I see this phase come up a lot 🤍

At this stage, your baby's sleep needs are changing. Two naps can push bedtime too late, but one nap can lead to overtiredness.

This creates a cycle where some days look fine, but nights become more unsettled.

What's making it worse

  • Switching fully to one nap too quickly
  • Letting the day become too long
  • Inconsistent nap patterns
  • Expecting immediate stability

What actually helps

This stage usually needs a flexible approach.

That might include:

With the right balance, things start to settle again.

How this might look in real life

This transition is one of the trickiest, and it usually shows up like this.

  • Baby refuses the second nap but is then overtired by bedtime
  • One-nap days feel too long and two-nap days feel too rushed
  • Baby is fine some days on one nap and falls apart on others
  • Bedtime has become a battle since you started dropping to one nap
  • You are unsure whether to push through or go back to two naps
