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


Definitely a must-have app for new parents  Ontheflyshutter  5 star

As first-time parents, we really appreciated the great insights this app had as we navigated the first few months of our baby. Moreover, it gave us plenty of peace of mind knowing that all of this has bona fide research to back it up. This is very important given all of the unscientific research, articles and books that “advise” you to do things that will have lasting negative consequences on your kid.


Wonderful app  BBA_TWIN  5 star

I like the new update ❤️


Scary accurate!  Tashanicole40  5 star

This app is seriously so spot on with how my LO is acting and what not that it’s scary lol. Well worth my money! They also have a book! Thank god for someone telling me about this app! Now I know when my babes going to have a rough week because of a leap.


Immensely helpful  Gshank  5 star

This app guided us through our little ones mental leaps and helped us understand what and why he is doing things. The leaps were accurate and it helped us help our little one reach his milestones on time. Love it!! Recommended it to many of my friends.


Wonderful App and a wonderful book  AishaWeiland  5 star

I love how it is synced with my phone's calendar so I know when will the next leap should be starting. It is pretty accurate. They are clear that it's not 100% exact. You give or take one week. Very informational and reassuring as to how my baby is to developing and what I can do to guide my baby through her leaps. Love it!


Not so sure  shainehmaidela  2 star

I've heard a lot about this app and my friends seem to rely on it a lot. They all said it was extremely accurate. I hate paying for apps which is why I was hesitant to buy it but I gave in because my son, who is 10 weeks, has been super fussy lately, eating all the time and not sleeping well at all and I wanted to see if this app would go along with what he's experiencing. Well it shows that he's currently going through a "sunny" phase but I completely disagree with that. I'll keep with the app for a few weeks to see how "accurate" it is but right now I'm not finding it that great. Please note that I did use my due date, not my son's birthday.

Dae Kwon

Not worth it  Dae Kwon  1 star

Echoing some of the other negative reviews. The app is not doing anything fancy. It sees how far along your child is based on expected birth date and provides information based on that. You can find similar information with a google search. I was expecting something similar to my wife’s period tracker app where it makes adjustments to the estimate based on when the actual periods occur. This app does nothing like that. The estimates are static.


App desperately needs a better writer  Theowwwww  2 star

The writing on this app really needs to improve. It happens pretty frequently that I really don't understand what a sentence or even a paragraph is trying to convey. The value of this app is solely through its words because it is relaying information that is helpful/ useful for parents. So it is critical to get someone who can write well and convey messages succinctly and clearly. That's my two cents. The app is great other than the not-so-good writing. But that's a major drawback.


Spot on!  Jenrenee79  5 star

This has been so helpful in gauging my daughter's development! Can't live without this app!

Pvz is awesome 1

Super helpful!  Pvz is awesome 1  5 star

And just enough info so I can actually read it even with my busy schedule.


Love the update!  Paulammiller  5 star

Hello! A friend referred me years ago to The Wonder Weeks app and I have used it for both of my sons (a now 4 year old and 13 month old) and I have loved it both times. I was actually sad when my first born had no more leaps on the app! Ha. But I think this most recent update has been the best one yet. It’s beautiful! And extremely user friendly with the summary, abilities etc easily accessible through the “more” tab. Excellent. Well done. The Wonder Weeks has helped us understand many tough times with our boys and it’s a great resource for all parents. Thank you!!


Disappointed  Newmumneedsleep  1 star

Not very user friendly. Info not quick and easy to read, although the chart is useful. Bite size bits of info formatted for phone would help frazzled mothers. More about selling their book. I would prefer a more expensive and extensive app than constant mentions of buying the book for more info


Invaluable for time poor  Darth_AUS  5 star

I bought the book, but didn't have time to read much of it. Getting some sleep was of more importance. The app was a great short version and reference tool. We've had the app for over a year now and it has been like clockwork for our babies development. A great source of information to know what to expect, when, and then see the development happen. Awesome!


Turns inexperienced parents into great ones!!  Rhinestone29  5 star

The wonder weeks is an absolute 'must have' for any parent. To understand what is happening in your baby's world and respond is to give them the best opportunities for health, happiness and development. We have shared with family members, and sit down together once a week to understand and adapt to our girls' development. Lots of ideas for me as a Dad to interact in a quality way. Get it and use it.


Love  160592maggott  5 star

This app is a god sent for us and is so accurate to my son.


Spot on  reviewer12345678901  5 star

I have found this to be spot on for my six month old. Every time we think her behaviour has been a little off, we look and see that she's going through a leap. A good companion to the book, although I tend to use the app more.


Crashes  emma.jayne  1 star

Unfortunately this latest update (unsure when it was) has caused the app to constantly crash. I can't get past the loading/main screen before it takes itself out of it again. frustrating as my girl is currently going through a leap and that information is great!


Won't open and has started crashing my phone  Tazza13zzzzz  1 star

Really disappointed for a paid app. Was working fine for ages but for over a month now it crashes my phone and won't open. Edit: have updated the app since the developer's response below and I still have the same problem. Can't open the app and it crashes my phone. I don't have this problem with any other app.

PauLy Big Nuts

Not that great  PauLy Big Nuts  2 star

I don't know why everyone wrote such a great review on this app. It's actually not that great. The information overload is not formulated properly. Useless stages of your babies development. Something like What To Expect or Baby Essentials is a better app for keep up with baby development.


App doesn't work  Goforthandconquer  1 star

Previous versions of this app worked great, and the information contained was great. But now it just won't open at all.

Not worth the $. Lastest update doesn't load  natalielui  1 star

For a paid app, I expected it to offer more than just information I could have easily found on the Internet for free. What a waste of $. What's more frustrating is that the latest update has caused the app the freeze on the main screen. Now I can't even access anything!! Don't waste your time & money. You'll find just more useful stuff online.


Love this app  Traxlera  5 star

Makes being able to understand your newborn or infant so much easier!
