Your baby's brain is developing. We'll tell you when (and why it matters)
Your baby is screaming. You've fed them, changed them, held them for two hours. Nothing works.
Baby Leaps tells you why — and when the next rough patch is coming.
Babies go through predictable "leap weeks" when their brain is rapidly developing. During these periods they're fussy, clingy, and hard to soothe. It's not something you're doing wrong. It's neuroscience.
KEY FEATURES:
Personalized Leap Timeline
Enter your baby's birth date and get a complete week-by-week breakdown of upcoming leaps — so you know exactly when to stock up on coffee and lower your sleep expectations.
Notifications & Reminders
Get alerts before leap weeks start. No more being blindsided by a suddenly inconsolable baby.
Home Screen Widget
Check your baby's current leap stage at a glance — no need to open the app at 3am with one eye open.
Friendly, Scribble-Inspired Design
Warm and informal, not clinical. Because parenting is already stressful enough.
Is it scientifically proven?
Developmental leap theory is grounded in decades of child psychology research. Not every leap hits every baby the same way — but millions of parents have found that knowing the pattern changes everything. "I can't do this" turns into "we've got three more days."
About the subscription
Baby Leaps is a yearly subscription — about the price of one cappuccino. Built to be a tool you actually rely on, not an app you pay for and forget.
---
You're tired. You're confused. Your baby is crying again for no apparent reason.
Baby Leaps won't make parenting easy. But it might make you feel like you actually know what's going on — and some days, that's everything.
Turn "what is happening?!" into "oh, that makes sense."
A yearly subscription is required to access the app. The app creator assumes no responsibility for any harm caused by potential errors or missing information within Baby Leaps.
