About Baby Weeks
Baby Weeks helps you follow your little one's first year, one week at a time. Enter your baby's date of birth and Baby Weeks shows exactly which week and day of life you're in today — with warm, week-by-week "what to expect" notes inspired by common developmental milestones and leaps. WEEK BY WEEK • See today's week and day at a glance • Gentle "what to expect" guidance for each week • Swipe to look ahead or back through the weeks TRACK THE DAY • Log feeds in a tap, with optional amount and notes • See how long it's been since the last feed — on every entry • Log diaper changes (wet / dirty), grouped by day • A simple next-feed estimate based on recent history MADE FOR FAMILIES • Add more than one child and switch between them • Share everything with your partner — log on either phone and it stays in sync via iCloud YOURS, PRIVATELY • Your data lives in your own iCloud — no account, no ads, no tracking • Soft pastel themes with light / dark / system appearance Baby Weeks offers general, friendly guidance inspired by common developmental milestones — it is not medical advice. Every baby grows at their own pace. If you have any concerns, talk to your pediatrician.
