Think of it as a portable, at-a-glance version of the calendar leap chart in The Wonder Weeks. Where the book describes in-depth and easy-to-understand terms the incredible developmental changes your baby goes through, the app is the perfect leap calendar companion to track your baby’s mental development (during the first 20 months).
By knowing what is going on inside the head of your baby, you can help him to make the leap more easily and stimulate his development.

The Wonder Weeks app helps new parents by:

- Calendar Showing when your baby makes a leap in his mental development

- What your baby can understand & learn after this mental leap

- What your baby can do after this leap

- What you can do to help your baby

This app is also a handy reminder for new parents when their baby’s brain is changing, or “leaping,” the baby is making a significant advance in mental development, and with each step forward comes a drastic change in the way your baby sees the world around him. Because these leaps come so quickly, the “new world” and new abilities can sometimes be scary, and the development can initially manifest in poor sleep, bad appetite, crying, clinging and crankiness – exhausting and frustrating mom and dad.

International experts on The Wonder Weeks:
 “This is a very practical and entertaining window into the baby’s first year and a half. van de Rijt and Plooij have observed and found the vulnerable times in an infant’s development that I independently came to in my book Touchpoints (Perseus Books Group). The authors’ observations and practical suggestions are wonderful.”
 -T. Berry Brazelton, M.D., professor emeritus, Harvard Medical School

"Anyone who deals with infants and young children will want to read The Wonder Weeks. This book will open parents' eyes to aspects of their children's growth, development, changing behavior, and emotional responsiveness that they might otherwise not notice or find puzzling and distressing."
 -Catherine Snow, Ph.D., Shattuck Professor of Education, Harvard Graduate School of Education

The Wonder Weeks Reviews


Very accurate  CAyed  5 star

I like how when my child is extra fussy I check the app, and he’s definitely going through a leap. As he grew I could tell when he was going though one but this app has helped me know the differences!


Great info, bad app  green_and_pink  1 star

The Wonder Weeks is great and I was loving that the app is more accessible than the book. However, the app keeps crashing and often it won’t open at all. Disappointed since the redesign


Exceptional info  Pinkraeja  5 star

The wonder weeks app has been incredible when we are feeling like terrible parents. It has been so reassuring that we are doing things fine and our little Man is just growing. The info has been spot on as the weeks have gone on! I’ll definitely be using this for the next little one!


Great app for busy Moms  JewelsBrake  4 star

This is a great app but if I had one complaint it would be that there is not enough reading material on each leap.


so helpful!  emlysk  5 star

so so helpful!


Finally!  Kellyserena81  5 star

I searched high & low for an app like this. I wish I would’ve found it sooner! I will definitely be recommending it to all my Mom friends.


SO accurate!  HB294  5 star

This app is freaky accurate! It’s been so helpful in understanding my little guy and what he’s going through at a particular time. Thank you Wonder Weeks!


Don’t waste your money!  250711  2 star

Purchased this app desperate to see why my baby is so fussy. I’ve been using it for seven months now and Haven’t read anything that would help me. It says the same things through each leap basically in different wording. According to this app, your baby is always in a “stormy” period. It really doesn’t explain to you how your baby is changing or the skills they’re mastering clearly. I regret paying for this app.


Helpful  postmatessucks2018  5 star

Helpful with my now toddler who is 4 now. And new baby who is 6 weeks. I forgot everything in 4 years so this made me feel less crazy remembering that there are so many stages that affect baby behavior


Very helpful!  Jag509  5 star

This app is very helpful when you’re trying to figure out what’s wrong with your kid. And it’s cool to learn what they’re going through developmentally.


Freezes phone  hbdjdjdd  3 star

Love this app but lately, like the last few months, it always freezes my phone and takes forever to load or just won’t load. Hoping fixes happen soon so it’s usable again!!


Incredibly Helpful  KDal77  5 star

As a first time mom this app has been so incredibly helpful. Understanding my son with each new leap has helped me so much and made me feel like I’m not failing as a mother.


Lifesaver!  CrunchyKim  5 star

Every parent needs this app! Im now using it on my second child and its an absolute lifesaver!


Spot On!  Bbboooggger  5 star

This app is spot on for developmental milestones.


Inaccurate  xokaleneox  1 star

I gave in and bought this when my second born was having a few days of being miserable hoping it would shed some light. He wasn’t even in “a leap” and now that he’s happy and sleeping great he’s supposed to be well into leap 4. Total hogwash imho. I will be deleting the app.


Did the text just change?  Birdmanjfc  2 star

This app was great (5 stars), but what used to be concrete suggestions for games to play during leaps like blocks that can be knocked down and peekaboo. Now it suggests that you pay attention to your baby and compliment them. That’s much less helpful (2 stars).


So good!  ShannanES  5 star

This app gives me so much insight into what my little one is experiencing down to the T! I read through information about each leap with a smile because each time it is spot on. I love the suggestions of activities and games to help support her development and the heads up about new mental and emotional leaps that may come with more fussiness or clinginess. It’s a great tool for new moms looking for in depth information and some direction for helping their little ones grow into creative and well adjusted people!


I’m not crazy!  ChristaChalene  5 star

My baby does get extra grumpy! And for good reason! Thank God there is a way I can understand her through all of this and help her better

Shann P

Love it  Shann P  4 star

I love this app but I really wish they would add the growth spurts to the calendar. That way it’s all in one place.


Love it!  Sedgwyck  5 star

It’s easier to figure out what my baby wants when I use the app, depending on what leap he has been going thru I can figure out if he needs more stimulation or more cuddle time or maybe just some alone time to decompress after a busy day.
