Sleep shapes a baby’s brain development, immunity, and mood. But “good” baby sleep looks very different at 2 months than at 18 months. This calculator turns the key signals — total daily sleep, night wakings, settling time, naps, and bedtime habits — into one clear score out of 100. It is built for parents, grandparents, and caregivers who want to know whether their baby’s sleep is on track.
Using age-specific targets from pediatric sleep guidance, the tool shows exactly which area needs the most attention and gives practical, gentle recommendations you can try tonight. Use the preset buttons to see typical newborn, infant, and toddler profiles, then adjust the numbers to match your own baby.
No sleep log is required — rough averages from the past few days are enough to get a useful starting point.

How to Read Your Baby’s Sleep Score
The score runs from 0 to 100. Scores of 85+ indicate excellent sleep patterns; 70–84 is good; 50–69 is fair; below 50 suggests the sleep routine may need real changes. The bar breakdown shows which component is dragging the score down, so you can focus on one change at a time instead of feeling overwhelmed.
How the Score Is Calculated
Each input is compared with age-adjusted targets and converted into points:
- Sleep duration (30 points): scores higher when total daily sleep falls inside the healthy range for the baby’s age.
- Night wakings (20 points): fewer expected night wakings as babies get older; frequent wakings cost points.
- Falling asleep (15 points): settling in 15 minutes or less earns full points; longer settling reduces the score.
- Nap pattern (10 points): points depend on whether nap count matches the typical range for age.
- Sleep habits (25 points): five checkboxes earn 5 points each for consistent routine, calm routine, sleep environment, independent settling, and separating feeding from sleep.
Worked Example
An 8-month-old sleeps 14 hours total, wakes twice at night, settles in 20 minutes, takes 3 naps, and has all five sleep-habit boxes checked.
Duration: 30/30. Night wakings: 20/20. Falling asleep: 10/15. Naps: 10/10. Habits: 25/25. Total = 95/100 — excellent.
If that same baby woke 4 times and settled in 45 minutes, the score would drop to 12 + 5 + 25 + 30 = 72 — good but worth a closer look.
Age-by-Age Sleep Targets
| Age | Total sleep (24 h) | Night wakings (typical) | Daytime naps |
|---|---|---|---|
| 0–3 months | 14–17 h | 2–3 | 3–5 |
| 4–11 months | 12–15 h | 1–2 | 2–3 |
| 12–24 months | 11–14 h | 0–1 | 1–2 |
Targets are based on general pediatric sleep guidance, including ranges from the National Sleep Foundation. Every baby is different, and these are starting points, not strict rules.
Tips for Better Baby Sleep
- Keep bedtime within 30 minutes of the same time each night, even on weekends.
- Use a short, calming routine: bath, book, lullaby, then bed.
- Make the room dark, cool (68–72°F / 20–22°C), and quiet. White noise can help.
- Put your baby down drowsy but awake so they learn to settle independently.
- Move the last feeding earlier so your baby does not rely on milk to fall asleep.
Frequently Asked Questions
What if my baby sleeps more than the target range?
A baby who consistently sleeps far above the range may be catching up after illness or a growth spurt. If very long sleep is paired with low energy while awake, check with your doctor.
How do I count night wakings?
Count any waking that needs your help to go back to sleep. Brief stirrings without crying or calling out usually do not count.
Can I use this calculator for a premature baby?
For premature babies, use the corrected age (age from due date) until around 2 years. Ask your pediatrician for the best guidance.
