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

Toots Kiss

Shouldn’t have to pay for info you can find through google!  Toots Kiss  1 star

There are literally only 9 leaps on here. AKA 9 paragraphs of info about the baby. That’s it!!! The info isn’t bad but I literally could have found this info on google if I just researched it on my own. I always thought spending money on apps was dumb- never did it until this app- now I totally regret it. And on top of that it’s kind of expensive for an app! 2.99?! Anyway, I regret it and it’s not worth it. Also the “storms” calendar doesn’t line up with my baby at all.


Good but inaccurate with due date  kahfydue  3 star

Good info but I put in the due date and it was a week off. He’s already going through the leap it’s saying. So I put in his birthday and it’s accurate now... I think it’s more accurate with bdays not due dates


Don’t buy into this crap  lmr2018  1 star

Maybe this app works for newborns or smaller infants, but once your baby starts teething/develops separation anxiety, all bets are off. There is no one size fits all app that will tell you what’s going on with your babe, he/she is an individual and will develop and hit milestones at their own pace.


So helpful!  Honeybee682  5 star

This app (as well as the book) has been so helpful for us. When my baby is extra fussy, I now know that he is on the verge of a mental leap, and it’s been crazy how accurate this has been. I highly recommend this app, plus I’d also recommend the book as well.


Brilliant app with deep insight into baby  holly.van.horn  5 star

This is my second child, but first child on the app. I absolutely find this app to be essential in tracking my child’s development. If you’re looking for a deeper understanding into the inner workings of your baby’s development, this app definitely provides everything you need to know. User friendly and engaging, the Wonder Weeks app makes tracking your baby a breeze!


Love it!  Walecky  5 star

I loved this app with my first, now we just had our second and I’ve redownloaded it! It may not have the exact dates correct, but they are within days of each other. Very helpful for when you can’t quite figure out why your baby is so fussy! 🤗


Not accurate  K_Nunley  1 star

I did what the app said to do by going off my daughters due date and not her birth date...well it’s extremely inaccurate. She’s 5 months old and it hasn’t accurately lined up once. She’s fussy in the “sunny” periods and and easy going during the stormy periods. I’m not sure right now whether she’s going through the 4th or 5th leap because it’s been so off. I was really hoping this app would be helpful, but it’s not at all if it doesn’t line up. All babies are so different so I guess it was wishful thinking that this could predict my daughters sunny and stormy periods.


Love this app  89303  5 star

Wonder weeks has helped us communicate and understand our little one so much better.


Unorganized  talm111  4 star

I LOVE the information this app provides but the layout isn’t very organized.


Not much content  Elle124444  2 star

Although the info is relevant and interesting, it’s pretty much the same bit of info for weeks on end. Once you end a leap period you get info for the next upcoming period and you can read it all in one sitting easily...and it doesn’t change until the end of the next leap. So in theory it’s nice to see what your baby is going through but it doesn’t give you anything new daily or even weekly. My baby is in her 5th leap right now so for 7 weeks I’m seeing the same blurb.


Great!  mamamurch  5 star

This has been so helpful to us as first time parents! App is easy to use and gives great information!


High recommended  MVDiego  5 star

This app helped my wife and I get a better understanding of what was happening and what to expect! They were spot on every time !


Amazing  lululove143  5 star

The wonderweeks is SPOT ON!

Great guide to parenting  Glens with  5 star

It might sound strange, but this app helps us understand just how to love our kids best. We used it with our first and were sad when there were no more leap/development overviews and tips after 18 months. We currently have a newborn and are glad to have this as a guide to best care for our new baby. LOVE!


Great for first time moms!  Iwishicouldfindagoodfontapp  5 star

I love being able to read about the development of my little one and knowing what to expect when she’s going through mental changes. It really helps me cater to her needs more.


Great!  kennedyblair  5 star

My baby is 5 months and we’ve had this app since about 2 months and it has been right on track just about every time with my little one! Great insight.


Self fulfilling prophecy  Bguggles  1 star

Dates didn’t match to fussy times at all and nobody has ever been able to scientifically replicate the fussy stages at the same times. The app also doesn’t let you rate it anything but 5 stars. The fact that I had to go through the App Store to leave an honest review lost them another star. The only semi reliable information is understanding what your child may be learning next and I did enjoy that part.


On point  Seriously❓  5 star

My daughter has hit every fussy stage almost to the day. It makes me feel so much better since she’s my first that I don’t have to rush her to the doctors every time she’s cranky because the app explains that it’s her cognitive leaps or learning separation anxiety or just moodiness so it’s such a weight off and I can see when it ends too! It gives me a light at the end of the tunnel. This app has been absolutely wonderful. I’m just sad I didn’t have it from the day I brought her home!


Doesn’t work  tinky865  2 star

This app is interesting but just after my sons 4th leap, he is more fussy. It’s completely inaccurate.


Great App for New Parents  kaschmitt15  5 star

I have followed the Wonder Weeks (book and app) for both of my kiddos. It has been really helpful in letting me know what skills they are working on and activities/games to help engage them. The leap alarm has also been a handy feature. The Wonder Weeks give awesome insight about baby brain development, skill acquisition, and the not so fun behavior that accompanies each. I would recommend purchasing the book, as it has a lot of extra information that the app does not.
