Learn all about the leaps and bounds and the fussy phases of your baby
Read the bestselling Wonder Weeks book here in this app
Take notes about a range of topics

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


Generic Info.  Brandy1921  1 star

Waste of money. You're better off reading your baby's horoscope.


Not a fan  Ransla007  2 star

I heard great things about this app but I don't like it at all. It's not user friendly. It tracks by your baby's due date instead of the actual birth date. It doesn't make sense to me because "40" week mark is an average. 38-42 weeks is considered full term. And it labels everything in weeks instead of months - I don't feel like doing math. It has very interesting information and facts but I feel like I'm trying to read through a text book - it's so long and boring. Just give me the highlights. I don't find the lay out user friendly or appealing. That's just my input. I much rather use Ovia Parenting.


Doesn't work with iPhone  Erin77826  1 star

App doesn't work with iPhones, updates don't fix the issue.

Life Saver!!!  Miss April Julien  5 star

This app has been spot on and has eased my mind on just about every leap! My daughter is currently completing leap 10! I have told all of my new mommy friends about this app!! Now make an app for toddlers!! Thank you Wonder Weeks! April and little Tatum


So interesting!  Savgoe  5 star

I've used Apple products since the 90's, but since the birth of the App Store- I've never cared enough to write a review... until now; I love this app! So informative and helpful with understanding my babies brain function and development. Also: I don't know why there's price complaints from other reviewers... you're typing on your $700 phone or your $1300 computer, but let's complain about $2? Okay. Anyway, love the app!

App is not working  True me1  1 star

Following the most recent update, the app will not launch when selected. Fix the app.


Not helpful  Cwat123  1 star

This app is not helpful at all. The information is very general and better info can be found on developmental stages by doing a quick Google search. The stormy and happy periods never match up with my child's moods. There are so many factors in child development and mood that this app does not take into account. This app can make you feel like your child is falling behind based on the skills they lost but ask any pediatrician out there and you will find that your child is completely fine. This app is a waste of time and money.


Very helpful for a first time mom like me  Allthat123  5 star

I love this app!

Autumn and Andrew

Great  Autumn and Andrew  5 star

Amazing!!! I love this app! I recommend it to all of my friends and family with babies!! It is always correct, accurate and right on time with the information!!! This is such a great help when you start wondering why your baby is fussy! And your baby really does know more and go through changes after each leap!! Thank you so much!! 5 out of 5 stars!!!


Useless  JessiBeeCat2016  1 star

This is the first time I've ever purchased an app and I regret it. The information here is so generic and broad and does not make any sense. Every baby is so different as to when they master skills and a calendar with clouds and rain telling me when my baby will be fussy? That is ridiculous and never matches his mood of course, there are just so many factors! If you want to know more about early childhood development and what kind of activities to do with them to help them work on their skills (which is what I thought this app was and why I purchased it), just Google it.


App keeps closing down  Chattysassy10  4 star

I've enjoyed this app as a resource, but after the last upgrade it doesn't open. It will begin to open and then shuts down. Please fix the glitch! I wanna read about my baby's upcoming wonder week!


App no longer opens after update.  thatkperson  1 star

Does not run in iOS 2.


Won't open  gridjess  1 star

Crashes immediately upon opening after this recent update.

Mom of 5 month old

Cost is Misleading  Mom of 5 month old  3 star

The app is great so far but I think on the description in the App Store it should say that you can read chapters from the Wonder Weeks at an extra cost. I feel miss lead about having access to the book. You can only read the intro chapters. Nothing about the actual Leaps. Disappointed.


4 stars could go to 5 with one change  Michayne71412  4 star

I love this app! It has helped me understand and better prepare for my sons neurological and developmental changes with greater ease. I can pin point signs of LEAP behavior and with this app better help him through a Leap and exercise his new skills. This app used to display my selected profile picture with ease now, since the upgrade the photo I select always gets super zoomed in and that makes for a terrible profile picture. Please fix that issue and I would gladly give it a 5 star rating. With that said this app was worth the 1.99.

Meh  Britt Hunt  2 star

I just bought this last night, and it continuously freezes my phone and force closes. I wish this wasn't an app I had paid for because I feel like it's a waste to delete it. I can't even get it to open without freezing.


Great app  Lindsey021216  4 star

This is a great app and seems to be pretty accurate for my baby. I'm not a fan of the update- I wish it still showed how many days left in her leap. Please please please bring it back!


Updates are making it worse  justminick  2 star

I liked being able to see how many days until a leap. Two versions ago I easily knew where my baby stood. The last update was this huge overhaul that was visually nice but was lacking a ton of content and quality. This version seems like a rush attempt to fix the problems of the last and is less nice to look at. The writing also seems weird and less thought out / professional - and the new movies don't show previews.


THANK YOU  MySuzannaO  5 star

Thank you so much for updating the app to a much more user friendly layout. This new update is amazing and I know exactly where everything is. I love that it shows the days remaining right there at top and I can put a pic of my baby girl! Really love this update. I love using this app again! Thank you for listening to your users!


Foreshadowing  kejostes  3 star

The new update is easier to navigate. However, I dislike that you cannot preview the next leap. Like your material says, not all children develop the same way, therefore, I should be able to preview the next leap to see if my child has progressed. Frustrating.
