Between 4-5 months old, babies experience the 4 to 3 nap transition, a natural part of their sleep development. This change can be tricky because it often coincides with the infamous 4-month sleep regression and an important schedule change. In this blog, you’ll find your new 3 nap schedule along with detailed steps and tips to help you successfully make the transition.
Why Does the 4 to 3 Nap Transition Happen?
As babies grow, their sleep needs shift. By 4 months, your baby’s brain is maturing, and they begin developing more structured sleep cycles. This often means they no longer need four short naps but instead benefit from three more predictable naps.
Signs Your Baby Is Ready for the 4 to 3 Nap Transition
Here are common signs that your baby might be ready to drop the fourth nap:
- Shortened or Skipped Naps: Consistently short (less than 1 hour) or missed naps may indicate readiness.
- Earlier Bedtime Makes Sense: If a fourth nap means bedtime after 7 pm, its’s time to drop it and shift to an earlier bedtime.
- Age: If your baby is 5 months old, it is time to drop the 4th nap. If they’re still 4 months old and taking longer naps a three nap schedule will be a better fit.
The 3 Nap Schedule
Shift to a By-the-Clock Schedule: Transition from tracking wake windows to following a by-the-clock schedule based on biological sleep times. This approach can help establish consistent nap routines and support better overall sleep.
Recommended 3 nap schedule:
Nap #1: Beginning between 8:30 and 9 am (1-2 hours)
Nap #2: Beginning between 12 and 1 pm (1-1.5 hours)
Nap #3: Beginning between 3:30 and 4:30 pm (30-45 minutes)
Watch for Sleep Cues: Keep these times in mind and watch your baby for early sleepy cues, such as staring into space or becoming less engaged, to determine the best time within the nap window to get them down. Learn more about sleepy cues here.
The 4-Month Sleep Regression Connection
The 4 to 3 nap transition coincides with the 4-month sleep regression, making this period feel extra challenging. During the regression, your baby’s sleep cycles change, leading to more frequent wake-ups and shorter naps.
