🌙 Free baby record tool

Baby Sleep Log

Record when a sleep period started and ended, see the duration from those timestamps, and keep optional notes. The tool describes the entries you save; it does not recommend wake windows, sleep schedules or sleep-safety practices.

A record, not a sleep recommendation

This tool calculates elapsed time between the start and end timestamps you enter. It does not decide how long a baby should sleep, when a baby should be awake, or what sleep arrangement is safe. Use an appropriate qualified source for health and safety decisions. For a connected daily record across feeding, sleep, diapers and caregiver handoffs, see BabyNest.
