Sleep Tip

Many babies can start learning to self-soothe. Consistent routines are key.

How Does the Sleep Calculator Work?

This calculator uses recommendations from the American Academy of Pediatrics (AAP) and the National Sleep Foundation (NSF) to determine sleep needs by age. Based on your child's age and wake time, it generates a personalized schedule with naps, wake windows, and a recommended bedtime.

Why Should You Track Your Baby's Sleep?

Tracking sleep helps you spot patterns that aren't visible day-to-day — regressions, nap transitions, and night wakings. With a week or more of data, you can see whether your baby is getting enough sleep, recognize when it's time to adjust the schedule, and share accurate information with your pediatrician.

Track Sleep with ParAI

ParAI tracks your baby's sleep automatically — just say "baby fell asleep" and the AI logs it. See 7-day trends, get regression alerts, and personalized tips for better sleep.
