Baby Sleep Schedule by Age: 0–12 Months

Baby Sleep Schedule by Age: 0–12 Months

If there's one thing new parents quickly learn, it's that baby sleep is anything but predictable. Just when you think you've cracked the code, your little one hits a growth spurt, a regression, or a developmental leap — and everything changes again.

Understanding a typical baby sleep schedule by age (0–12 months) can help you set realistic expectations, spot patterns, and gently guide your baby toward healthier sleep habits. Here's a month-by-month look at what to expect during the first year.

Newborn: 0–2 Months

In the earliest weeks, babies sleep a lot — roughly 14 to 17 hours per day — but in short, irregular stretches of two to four hours. Their circadian rhythm hasn't developed yet, so they don't know the difference between day and night.

What to expect:

• No predictable schedule — sleep happens around the clock
• Wake windows of just 45–90 minutes between naps
• Frequent nighttime feedings (every 2–3 hours)
• Lots of "drowsy but awake" practice, if your baby tolerates it

Tip: Help your newborn start distinguishing day from night by keeping daytime bright and stimulating, and nighttime calm and dark. A soothing bedtime cue — like a quiet piano melody — can signal that it's time to wind down, even at this young age.

3–4 Months: Emerging Patterns

Around three months, many babies start consolidating sleep into longer nighttime stretches of five to six hours. Total sleep is typically 14 to 16 hours, with three to four naps during the day.

This is also the age of the infamous 4-month sleep regression. Your baby's sleep architecture is maturing, which means lighter sleep cycles and more frequent wake-ups. It's temporary, even though it doesn't feel like it at 3 a.m.

Wake windows: approximately 1.5–2 hours.

5–6 Months: Settling In

By five to six months, most babies are ready for a more structured routine. They typically need 12 to 15 hours of total sleep, including two to three naps. Some babies begin sleeping through the night (six to eight consecutive hours), though many still wake for a feeding.

This can be a good time to establish a consistent bedtime routine — bath, pajamas, a story, and gentle music. Consistency is what teaches babies to associate these cues with sleep. Many parents find that soft instrumental music, like the piano lullabies from Musiscape, helps create a calming transition from play to rest.

Wake windows: approximately 2–2.5 hours.

7–9 Months: Two-Nap Transition

Between seven and nine months, most babies drop to two naps per day (morning and afternoon) and sleep about 12 to 14 hours total. Nighttime stretches get longer, and some babies are sleeping 10–12 hours overnight.

You might encounter another regression around eight to nine months, often tied to separation anxiety, crawling, or pulling to stand. Your baby's brain is busy, and that excitement can spill into nighttime wake-ups.

Wake windows: approximately 2.5–3.5 hours.

10–12 Months: Approaching Toddlerhood

By the end of the first year, most babies are solidly on a two-nap schedule with total sleep around 12 to 14 hours. Bedtime often falls between 6:30 and 8:00 p.m., and many babies sleep through the night reliably.

Some babies flirt with dropping to one nap around 12 months, but most sleep experts recommend holding onto two naps until closer to 14–18 months. A baby who suddenly refuses a nap isn't necessarily ready to drop it — it may just be a phase.

Wake windows: approximately 3–4 hours.

Remember: Every Baby Is Different

These guidelines are based on averages from organizations like the American Academy of Pediatrics and the National Sleep Foundation. Your baby may need slightly more or less sleep, and that's completely normal.

A few universal principles that help at every age:

• Watch for sleepy cues — yawning, eye rubbing, fussiness
• Keep the sleep environment consistent — dark, cool, and quiet
• Build a short, repeatable bedtime routine
• Be patient with regressions — they pass

Sleep is one of the hardest parts of the first year, but also one of the most rewarding to figure out. Trust your instincts, lean on the data when it helps, and give yourself grace on the tough nights. You're doing a wonderful job.
