Baby Nap Schedule Calculator
Medically reviewed by Safi Ullah Khan
4 months: wake window 90–150 min. common practice, not an official standard. Typical naps: 3–4.
If wake-up is 07:00, the next nap window is about 08:30–08:45. Later nap starts (sample): 08:30, 11:15, 14:30. From 4 months, many families aim for bedtime between 18:30 and 20:30.
Place baby on their back on a firm, flat surface with no soft bedding for every sleep (AAP).

Quick answer: A nap schedule calculator turns your baby's age and morning wake-up time into a sample day of naps and a bedtime. Most babies take 4-6 naps at 1-2 months, 3-4 at 4 months, 3 at 5-6 months, 2 from about 7-9 months and 1 nap somewhere between 12 and 18 months. Adjust to your baby's cues.
TL;DR
- Pick age and wake-up time; the tool lays out naps with age-typical wake windows.
- Nap transitions (4→3, 3→2, 2→1) happen over weeks, not overnight.
- Bedtime usually lands 11-12 hours after morning wake-up from about 4 months.
This nap schedule calculator builds a realistic sample day for your baby: how many naps, roughly when, and when bedtime might fall. It's a template to start from, not a timetable your baby must follow. Newborn sleep is irregular for the first couple of months, and that's normal.
How to use the nap schedule calculator
- Enter your baby's age (corrected age if born early).
- Enter the usual morning wake-up time.
- Optionally set typical nap length (short, medium, long).
- Read the sample schedule: nap start times, wake windows and bedtime.
- Print it or share it with your partner or caretaker.
How the nap schedule calculator works
The calculator chains wake windows and nap lengths for the age band:
t = wake_time
for each nap: nap_start = t + wake_window[i]; t = nap_start + nap_length[i]
bedtime = t + last_wake_window (clamped to 6:30-8:30 pm from 4 months)
| Age | Naps | Typical nap length | Example bedtime (7 am wake) |
|---|---|---|---|
| 0-2 months | 4-6+, irregular | 30 min-3 h | no fixed bedtime yet |
| 3-4 months | 3-4 | 45 min-2 h | 7:00-8:00 pm |
| 5-6 months | 3 | 1-2 h (third nap short) | 6:30-7:30 pm |
| 7-9 months | 2-3 | 1-1.5 h | 6:30-7:30 pm |
| 10-12 months | 2 | 1-1.5 h | 6:30-7:30 pm |
| 13-18 months | 1-2 | 1.5-3 h for one nap | 6:30-7:30 pm |
Nap counts and lengths are common practice ranges, not official guidance; total daily sleep follows the AAP-endorsed ranges.
Worked example
Omar is 8 months old and wakes at 6:30 am. With 2.5-3.5 hour windows and 1-1.5 hour naps, the tool suggests nap 1 at 9:15 am, nap 2 at 1:30 pm and bedtime around 7:00 pm. If nap 2 runs long, it moves bedtime later by up to 30 minutes.
Signs of a nap transition
Your baby may be ready to drop a nap if they regularly take a long time to fall asleep, skip a nap, or start waking early or at night because day sleep is too long. Transitions usually take 2 to 6 weeks. Some days will need the extra nap. The baby sleep schedule by age pages show each stage.
Daycare and caretakers
If a nanny, grandparent or daycare handles naps, share the sample schedule and log naps in one place. Tot's caretaker sharing lets them add naps that you can see later.
Safe sleep and car seat naps
Naps in car seats, swings and slings should be supervised and moved to a firm, flat crib or bassinet when possible, the AAP advises. Read safe sleep basics.

FAQ
How many naps should a baby take?
Commonly 4-6 at 1-2 months, 3-4 at 4 months, 3 at 5-6 months, 2 from around 7-9 months and 1 between 12 and 18 months. Every baby is different.
When do babies drop to 2 naps?
Usually between about 6 and 9 months, when the third, late-afternoon nap becomes hard to fit in.
When do babies go to 1 nap?
Most move to one midday nap between 12 and 18 months.
How long should naps be?
Anything from 30 minutes to 2 hours can be normal. Total sleep across 24 hours matters more than a single nap's length.
Should naps be at the same time every day?
A predictable rhythm helps many babies from about 3-4 months, but newborns can't follow a clock. Aim for a flexible routine rather than exact times.
