Frequently Asked Questions
How many hours should a newborn sleep?
According to the CDC and American Academy of Sleep Medicine, newborns (0–3 months) need 14–17 hours of sleep per day. Our dataset of 380 tracked newborn sleep sessions shows an average of 15.5 hours, with sleep spread across 6–7 naps throughout the day and night.
When do babies typically sleep through the night?
Most babies are developmentally capable of sleeping a 6-hour stretch by 3–4 months, and a full night by 6 months according to AASM guidelines. In our data from 3,317 tracked sessions, the average number of night wakings drops from 5.2x at 1 month to 2.3x by 11 months.
How many naps does a 6-month-old need?
A 6-month-old typically takes 2–3 naps per day totaling 3–4 hours of daytime sleep. Our tracked data shows an average of 2.5 naps per day at 6 months, each lasting approximately 60–90 minutes.
What is a wake window?
A wake window is the amount of time a baby can comfortably stay awake between sleep periods before becoming overtired. Wake windows increase with age — from 45–60 minutes for newborns to 3–4 hours by 12 months. Watching wake windows (rather than the clock) is the most reliable way to catch the optimal sleep window.
What is a sleep regression?
A sleep regression is a period when a baby who was sleeping well suddenly wakes more frequently or resists sleep. Common regressions occur at 4 months, 8–10 months, and 12 months, typically lasting 2–6 weeks. The 4-month regression is developmental and permanent — it marks a shift to adult-like sleep cycles.
