Getting your baby on a sleep schedule is one of the biggest challenges of early parenthood. The good news is that babies naturally develop patterns as they grow. Understanding age-appropriate sleep needs helps you set realistic expectations and support healthy sleep habits.
Newborn (0 to 3 Months)
- Total sleep: 14 to 17 hours per day
- Naps: 4 to 6 short naps (30 minutes to 2 hours each)
- Longest stretch: 2 to 4 hours at a time
- Wake windows: 45 to 90 minutes
Newborns do not have a predictable schedule. They sleep in short bursts throughout the day and night, waking primarily for feeding. At this age, follow your baby's cues rather than trying to enforce a strict schedule.
3 to 4 Months
- Total sleep: 14 to 16 hours per day
- Naps: 3 to 4 naps per day
- Longest night stretch: 4 to 6 hours
- Wake windows: 1.5 to 2 hours
Around 3 months, many babies start developing a more predictable pattern. Some babies begin sleeping longer stretches at night, though night feedings are still normal. This is also when the 4-month sleep regression commonly occurs, disrupting established patterns. Read our baby sleep regression guide to learn what to expect and how to handle it.
4 to 6 Months
- Total sleep: 13 to 15 hours per day
- Naps: 3 naps per day (morning, midday, late afternoon)
- Longest night stretch: 6 to 8 hours
- Wake windows: 2 to 2.5 hours
Many babies are capable of sleeping 6 to 8 hours at night by this age. The third nap of the day (late afternoon) is often the shortest and may become a "catnap." Bedtime typically settles between 6:30 and 8:00 PM.
6 to 9 Months
- Total sleep: 12 to 15 hours per day
- Naps: 2 to 3 naps per day (transitioning to 2)
- Longest night stretch: 8 to 10 hours
- Wake windows: 2.5 to 3 hours
Most babies drop to 2 naps between 6 and 9 months. The 3-to-2 nap transition can be tricky and may temporarily cause overtiredness or early waking. Many babies at this age can sleep through the night, though some still need 1 feeding.
9 to 12 Months
- Total sleep: 12 to 14 hours per day
- Naps: 2 naps per day (morning and afternoon)
- Longest night stretch: 10 to 12 hours
- Wake windows: 3 to 4 hours
By now, most babies have a solid 2-nap schedule. Morning naps are usually 1 to 1.5 hours, and afternoon naps are similar. Nighttime sleep consolidates to 10 to 12 hours for many babies.
12 to 18 Months
- Total sleep: 11 to 14 hours per day
- Naps: 1 to 2 naps (transitioning to 1 around 14 to 18 months)
- Night sleep: 10 to 12 hours
- Wake windows: 4 to 5.5 hours
The 2-to-1 nap transition usually happens between 14 and 18 months. When your toddler drops to 1 nap, it typically happens midday and lasts 2 to 3 hours. This is a significant transition and can take 2 to 4 weeks to fully settle.
Tips for Every Age
- Watch wake windows: The time between naps matters more than clock time. An overtired baby fights sleep harder.
- Consistent bedtime routine: A simple, consistent routine (bath, book, song) signals that sleep is coming.
- Dark room: Darkness triggers melatonin production. Use blackout curtains for naps and nighttime.
- White noise: Consistent white noise helps babies sleep through normal household sounds.
Track Sleep Patterns with BabyInsight
Tracking naps and nighttime sleep manually is exhausting when you are already sleep-deprived. BabyInsight's sleep tracker makes it simple with one-tap logging, and the SleepSync feature learns your baby's unique patterns to predict optimal nap windows.
You can see daily SleepScores, track wake windows in real time, and get personalized suggestions based on your baby's actual sleep data, not just generic age recommendations. For recommended totals at each stage, see our guide on how much sleep your baby needs.
