Awarded coolest app for moms 2012!
"The Wonder Weeks app can be a lifesaver for parents during those times of wondering what on earth is going on."


The Wonder Weeks worldwide bestselling baby app is now a (native) iOS app! A personalized daily calendar of your baby’s development that will keep you informed about the (mental) leaps and bounds and the fussy phases of your baby -- any time of day or night. This baby calendar app won prizes in several countries as BEST PARENTING APP!


-Add the picture of your baby

-Calendar of your baby 

-new design, lots of new features!

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

  • Great App!

    by laportes21

    I could set my watch by this app for when my daughter starts her Leaps! It's so nice to know what to expect & when to expect it. The only thing I wish they didn't remove with the recent update is the countdown to how many days remain in the current leap. Other than that, it's helped us greatly.

  • Settings for leap countdown

    by Hannahbunny85

    The wonder weeks app is great! The only thing is, my baby is almost three weeks ahead in it... If there was some way to type in when your baby has gone into a leap, so you can start the count down early, the app would be WELL worth all of my time. Over all, it's very informational, and handy.

  • Like it, but update was annoying

    by Tortelinatreefrog

    The info is handy, but you can easily get the book used. The most recent update deleted the children I was tracking so I had to re-enter info. That's just annoying.

  • Great for first time Moms

    by VelasquezSaedio

    This really helped me understand what was going on with my baby. Especially being a new mom! I recommend it highly to new parents. I see others had glitch problems, I personally haven't had any.

  • Crashes

    by Lisa Harden

    Love the information this app gives. However I can't change the gender so that's slightly disappointing (despite closing the app and restarting my phone) but it's still a great app.

  • New update won't let app open

    by Slusg

    Great app when working

  • Best app ever!

    by nataliainzunza

    Love this app. Had to re-install to make it work after the update. Aside from that it's been extremely accurate with my son and has helped me see his fussy periods come before they do! Also really love the new look. Definitely worth the money!

  • Crashes!

    by Eephilly

    Just installed the latest update and app crashes every time I try to open it. Hope this is fixed soon as we are starting a new leap! this app. It's been spot on with all my little guy's leaps. UPDATE: Uninstalled and reinstalled and app works fine now. Silly that this is the workaround...should have had another update to correct the problem. Had to re-enter information and don't think the changes are that significant but still love the information in this app.

  • Crashing

    by Megan Adams

    Love the app but keeps crashing with the new update.

  • This was a decent app, but not anymore.

    by Nyreth

    The latest update has rendered this app completely useless. How and why did the publisher and developer allow this to happen, especially when it is such a widespread problem? I would have given this 4 stars before, but not anymore. I hope this doesn't become a trend for updates from this publisher. (I am pointing the finger at Domus Technical because their website claims they will handle quality control and end-user communication.)

  • New update crashes!!!

    by jillbird83

    I love this app, that's why I have it 5 stars. I beg you to fix it. Since the newest update it just immediately crashes!!! Please fix!!!

  • Love the new version

    by Brazuca85

    I love the looks of the new version (v. 4) and how easy it is to go through the app now. I also had the problem with the app crashing when I first updated it, but then I deleted this app and reinstalled it. Problem solved, this new version works great with my iPhone 5!

  • Love the app but crashing after update

    by Aggiezg05

    The app won't even open after the update! Please fix this soon! Other than that, love the app!

  • Great app but update needs fixed

    by purtytxrose

    Really liked this app & found it very helpful prior to the update. However, since the update, every time I try to access it, it crashes. I can't even get past the welcome screen...

  • Best. App. Ever.

    by kristenboe

    I am so glad a friend told me about this app. It not only describes my daughter's behavior to a T but also the exact skills she is learning and personality quirks at the exact time she does it too. It's great to know ahead of time when a "storm" is coming and it allows me to have a lot more understanding, patience, and empathy for her because now I know why she's acting the way she does. I have told all of my other mommy friends about it and they all love it too. Well worth any cost and I'll probably be buying the book as well!

  • Not worth the money

    by The Jordan

    This app really isn't very helpful. It was a waste of money, in my opinion.

  • Don't bother

    by Imjilyan

    This app (unfortunately) is a waste of time and money. I got it as I heard about "wonder weeks" and figured the app was inexpensive so why not but truth is it's a waste. Nothing I couldn't have gotten on the web and no great direction re: what to do (the "Help" tab is really of no help. There is a book too but what new mom has time read? Not this one :) Anyway, save your money and search the web for such info.

  • Latest update made this app useless

    by Jerharvey

    I loved this app because it was so easy to track my baby's progress through the leaps. The latest update ruined all that. The app used to tell me how long till the end of the current leap and how long to the next leap if in between, but now it only tells how long till the next leap. It's more important for me to know when the current leap will end than when the next leap will start. The chart no longer shows the baby's spot on the chart. It's broken.

  • Not much info

    by Mariayoani

    The app doesn't go day by day . It goes period of few weeks & gives u a general non specific idea about that period . Dont think its worth the money !!!

  • Disappointed

    by Mrs_Macaggums

    App keeps closing when I am able to open it but most of the time it won't even open. Glad I wasted my money.

  • Great, but update changed everything

    by Poverbaugh

    Loved this app to help know what developmental "leaps" my new baby is going through, but with the app update a lot of the info was taken away/doesn't work. Plus, the chart used to show exactly where your baby is on the chart which made it easy to see how long until the next leap, and that graphic has been taken away.

  • Have to delete app and install it again

    by anna cecilia lindqvist

    In order for it to work. Happens with many apps after the update. Very annoying! Love the app though.

  • Ugh!

    by Laurenash90

  • With the latest update the app now crashes

    by Guidooo77

    I did like this app, but now can't launch it because it crashes. I am on an iPhone 4S with iOS 7.

  • :(

    by Raging Ramboner

    App crashes as soon as I open it now after updating!

  • Not great

    by Lauren Becker

    So I sadly bought this app a while ago and it isn't great. I have a bunch of friends who seemed to like it but it hasn't ever been correct with my son. It says we are in a leap and he has been doing those new things for weeks. Also, the new update makes it crash all the time! Thanks for the waste of money

  • Update crash

    by Clec2010

    This app will not load ever since the update today! Please fix soon! This is a waste of money otherwise!

  • Not Working

    by Addicting

    Amazing app! but Just updated it and now it's not working. Please fix ASAP!

  • Update doesn't work

    by FrancophilePA

    The app won't even open anymore. Please fix!

  • Closing

    by Jelicas82

    New update is terrible. I can't even open the app anymore. It closes every single time I try opening it. I've even tried restarting my phone. Nothing. And I paid for this!

  • Does not work after update!

    by Kimberly Neal

    Love this app but unfortunately will not open after today's update...

  • App crashes

    by HedaBee

    Worked great before update but now it crashes whenever I open it.

  • Won't open!

    by Sylvlana

    Just downloaded the latest update and now the app won't open. When I tap it it comes up and closes right back immediately. :( Any chance this could be fixed soon? Thanks.

  • Not working

    by Brum82

    Downloaded update and now the app closes as soon as I open it. Hopefully this can get fixed soon.

  • After the updated the app never open pone again.

    by Oscar Ocasio

    After the updated the app never open again. Wait for the next update or until they fix the problem

  • Google gives me more

    by KalyMarie

    I heard a lot of great things about this app, but it unfortunately doesn't live up. First it is off and I would recommend putting an actual birth day rather than due date. My son was 2 weeks early and by due date the app is far behind. But the info given isn't anything special. You could find it by googling "6 week milestones".
