You're awake at 3 AM. Your baby won't sleep. You're Googling frantically, finding contradictory advice from strangers on the internet. Some say let them cry. Others say never let them cry. Some say the wake window is 45 minutes. Others say 2 hours. What you actually need: A calculator that knows your baby's age. A guide grounded in pediatric sleep research. No email walls. No fake urgency. No fake sleep coach credentials. That's Baby Sleep Tools.
4 Free Calculators:
Wake Window Calculator — Find the optimal minutes of awake time between sleeps, tuned to your baby's exact age (0–24 months)
Nap Schedule Generator — Generate a full-day sleep schedule from a single morning wake time
Sleep Regression Checker — Diagnose whether your baby is in a 4, 8, 12, or 18-month regression
Bedtime Calculator — Work backwards from wake time to find the right bedtime tonight
