Optimizing baby sleep timing for quality and duration
Core Idea: Managing a baby's sleep schedule according to age-appropriate wake windows is fundamental to all other sleep techniques, as overtired or undertired babies will struggle to fall and stay asleep regardless of other interventions.
Key Elements
The Importance of Timing
- Sleep hormone production depends on appropriate timing
- Overtired babies produce stress hormones that fight sleep
- Undertired babies lack sufficient sleep pressure to fall asleep
- Sleep becomes increasingly time-dependent as babies mature
- Appropriate timing is foundational to all other sleep tools
Wake Windows by Age
- 0-3 months: Highly variable, generally 1-2 hours (newborns are inconsistent)
- 3-6 months: 2-3 hours between naps, with pre-bedtime wake time slightly longer
- 6-9 months: About 3 hours between naps
- 9-12 months: About 4 hours between naps
- 1-3 years: 4-6 hours of wake time before bed
Signs of Overtiredness
- Fussiness and irritability
- Difficulty settling even with assistance
- Short naps (less than one sleep cycle)
- Early morning wakings
- Frequent night wakings
- Hyper behavior or "second wind"
Signs of Undertiredness
- Resistance to sleep attempts
- Playing in crib/bed
- Taking long time to fall asleep
- Short naps due to insufficient sleep pressure
- Progressive shift to later bedtimes
Pre-Bedtime Wake Period
- Should be 1.3-1.5 times longer than other wake periods during the day
- Creates sufficient sleep pressure for consolidated night sleep
- Too short: difficulty falling asleep
- Too long: overtiredness leading to fragmented sleep
