Baby Tracker makes it simple to record feedings, sleep, diaper changes, pumping, growth, health, and milestones—all in one place. Designed by busy parents, for busy parents, it keeps everyday tracking quick, clear, and easy to share with caregivers. WHAT’S NEXT One more helpful cue for your baby’s day. What’s Next uses on-device AI to turn recent activity logs into personalized timing cues. Depending on what you’ve logged, it may show: • A likely wind-down window before sleep • An estimated length for the next nap or sleep • An approximate wake-up window • An estimated time for the next feed • A suggested time to check the diaper Cues can start appearing after just a few logs. Regular, complete logging helps make them more personal to your baby’s developing routine. What’s Next is optional. You can hide it in Settings → Preferences. GUIDANCE, NOT A SCHEDULE Use What’s Next alongside your baby’s own cues and your judgment—not as a fixed schedule or instruction. What’s Next is not medical advice. Contact a healthcare professional if you have concerns about your baby’s health, sleep, or feeding. PRIVATE BY DESIGN What’s Next cues are created directly on your device. Your baby’s logs aren’t sent to us to generate them.
