How to Use the Newborn Sleep Schedule Calculator
When you're raising a newborn, it's often hard to tell whether your baby is getting enough sleep, or how many naps are appropriate for their age. This calculator takes your baby's age in months and shows the typical recommended total daily sleep along with a nap and nighttime sleep schedule guide for that age range.
The guidelines are split into three age bands. Babies 0-3 months typically need 14-17 hours of sleep a day, spread across 4-5 naps totaling about 6-7 hours, with 8-9 hours of night sleep (including frequent wake-ups). From 4-11 months, total sleep drops to 12-15 hours with 2-3 naps, and night sleep stretches to 10-11 hours. After 12 months, total sleep settles to 11-14 hours with just 1-2 naps, as the pattern shifts more heavily toward nighttime sleep.
Keep in mind these figures are general recommendations drawn from common pediatric and sleep guidelines, and every baby has a different temperament and developmental pace, so it's fine if your baby doesn't match these ranges exactly. Use this as a reference while adjusting feeding intervals, nap timing, and daytime activity to find the rhythm that works best for your baby. As your baby gets older, overnight feedings naturally taper off and stretches of unbroken sleep get longer, so trying different ages in the calculator can help you preview what's coming next.
