BabySleepCalc: Sleep Planner

Wondering when your baby should sleep after waking up?

BabySleepCalc is a gentle sleep planning companion that estimates the next nap or bedtime from your baby’s age and last wake-up time. Age-based wake window references help you see a recommended sleep time and a comfortable settling range at a glance.

Every baby’s sleep rhythm can vary from day to day. Use the estimates together with your child’s tired cues, such as yawning, rubbing their eyes, or fussiness.

Sleep times shown in this app are general developmental references and are not medical advice. Every child is different. If you are concerned about sleep or health, consult a pediatric professional.
