Chapter 2: Sleep Regressions
The Night Shift Stage
Your child's brain is growing fast — and sleep is the first thing to feel it.
Your child is going through a developmental leap that's disrupting sleep. This is temporary and neurologically normal — their brain is growing faster than their body can keep up. Sleep regressions typically last 2–6 weeks and coincide with major milestones.
Try this first
Try moving bedtime 20 minutes earlier for 5 nights. Overtired children produce cortisol, making it harder — not easier — to fall asleep. Counterintuitive, but it works.

Your next steps
This week's rhythm
Shift bedtime 20 min earlier. No other changes.
Audit environment: noise, light, temperature.
Review wake window log. Adjust nap timing if needed.
Evaluate: if no improvement, consider a sleep consultant.
When to seek support
Regression lasting more than 6 weeks (may signal an underlying issue)
Snoring or mouth breathing during sleep (worth a pediatric check)
Sudden regression after a period of solid sleep (often tied to a new milestone)
The science behind it
Sleep regressions typically last 2–6 weeks and coincide with developmental leaps.
Consistent bedtime routines reduce night wakings by up to 40% within 2 weeks.
White noise at ~65 dB mimics the womb environment and extends sleep cycles.
Overtired children produce cortisol, making it harder — not easier — to fall asleep.
