Frequently Asked Questions
What are wake windows?
Wake windows are the periods of time your baby is awake between naps. Age-appropriate wake windows help prevent over-tiredness: newborns need just 45-60 minutes awake, 6-month-olds need 2-2.5 hours, and 12-month-olds need 3-4 hours between sleeps.
When do babies drop to one nap?
Most babies transition from two naps to one between 13-18 months. Signs your baby is ready include: consistently resisting the second nap, taking very long to fall asleep for naps, or sleeping well with just one midday nap. The transition period can take 2-4 weeks.
How much sleep does a newborn need?
Newborns (0-3 months) need 14-17 hours of sleep per day, split between nighttime and multiple naps. Newborn sleep is irregular - they typically sleep in 2-4 hour stretches around the clock. A predictable schedule usually emerges around 3-4 months.
