Key Takeaways
- Newborns sleep 14–17 hours per day in short 2–4 hour bursts
- Most babies start sleeping longer stretches (5–8 hours) around 3–6 months
- Sleep regressions at 4, 8, and 12 months are normal and temporary
- Always follow AAP safe sleep guidelines: back to sleep, firm mattress, empty crib
If you're a new parent staring at the ceiling at 3 AM wondering whether your baby's sleep is "normal" — you're not alone. Newborn sleep is unpredictable, but understanding the patterns can help you feel more in control.
How Much Sleep Do Babies Need?
According to the American Academy of Pediatrics (AAP), here's what to expect:

| Age | Total Sleep (24h) |
|---|---|
| 0–3 months | 14–17 hours |
| 4–6 months | 12–16 hours |
| 7–12 months | 12–15 hours |
Newborns sleep in short bursts of 2–4 hours because their tiny stomachs need frequent feeding. This is completely normal, even though it doesn't feel like it at 2 AM.
Sleep Patterns by Age
0–6 Weeks: Survival Mode
There's no schedule yet — and that's okay. Your baby doesn't know the difference between day and night. Focus on feeding on demand and sleeping when the baby sleeps. Wake windows are only 45–60 minutes.
6–12 Weeks: Patterns Emerge
You'll start noticing longer stretches at night (3–4 hours). A bedtime routine becomes helpful — bath, feed, dim lights, white noise. Wake windows extend to 60–90 minutes.
3–6 Months: The Sweet Spot
Many babies start sleeping 5–8 hour stretches at night. Naps consolidate from 4–5 short naps to 3 predictable ones. This is when a consistent schedule really pays off.
6–12 Months: Longer Nights, Fewer Naps
Most babies can sleep 10–12 hours at night with 2 naps during the day. Sleep regressions at 4, 8, and 12 months are common — they're temporary and usually linked to developmental leaps.
Signs Your Baby Is Tired
- Rubbing eyes or pulling ears
- Yawning or fussiness
- Looking away or losing interest
- Jerky movements or clenched fists
Catch the window
An overtired baby is harder to put down than a tired one. Watch for early cues and start the nap routine before fussiness escalates.
Safe Sleep Guidelines (AAP)
- Always place baby on their back to sleep
- Use a firm, flat mattress with a fitted sheet
- Keep the crib empty — no blankets, pillows, bumpers, or toys
- Room-share (but not bed-share) for at least the first 6 months
- Offer a pacifier at nap and bedtime
When to Talk to Your Pediatrician
Every baby is different, but reach out if your baby:
- Sleeps significantly less than the ranges above
- Has trouble breathing during sleep (snoring, pauses, gasping)
- Is extremely difficult to wake for feedings in the first few weeks
- Shows a sudden change in sleep patterns
