Amazing App but some issues commenting

The info in the app and book are insightful and huge help in figuring out how to help my son grow but having annoying time posting in the forum. Anytime I click the comment button my response bar disappears until I hit done. It’s very frustrating but other than that the app is incredible and make sure you read the book as well.

Great for new and experienced parents

I’ve been using this app since my first child was born over five years ago! It has helped me so much, both in mentally preparing for and better understanding those fussy periods when they’re inconsolable, and in finding ways to stimulate their developing brains. Now, I’m using it with my third and final child, and it continues to help me strengthen my bond with them.

I love this app!

I love this app! It is very helpful with explaining certain behavior at different times, to help parents understand what babies and young ones are experiencing, and gives you great ideas of things to do with your little ones during each phase!

It’s been on loading since 2025 smh

AMAZING- This app is GOLD!!

I discovered this app with my firstborn 13 years ago and was fascinated by how accurate it was. It did away with all the "wondering" I had about what my son was thinking as a baby, when he was happy or sad, etc. and told me more than I would ever know or could ever know otherwise. It was spot-on. I remembered it when I had another baby, who is just now 1 year old. Even her dad is amazed and his jaw drops every time I read to him about a current leap. It's one of the only apps that, hands down, is worth every penny of the small cost. It's literally like a psychic reading into your baby's everyday life, and that's priceless. I love that they've incorporated suggested playtime activities to do with your child to help them practice their new skills each leap--this insight also helps me know which toys she will be most satisfied and interested in if I need to get things done around the house. This app is GOLD!! Get it today!!
