Keep track of your baby’s mental development
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

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.

Miss me yet? Hi mommy,, I know you like MaMa, it’s not better than mommy which I didn’t car for I just like Mama more. I am looking forward to tonight even!! I have shoes, Dream, need. I can’t tell you tgbum getting better it worse.


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.


Wow  ndiyahakes  5 star

Eerily accurate!!

E J 88

Pretty good  E J 88  4 star

I like this app- it seems scarily accurate The only thing I wish we could do is write notes on specific days - for instance one day when my bub was being particularly fussy it was during a leap but not a stormy period so I wanted to write it on that specific day for reference. It would be good if you could select a period on the chart and make a note for yourself


Dumbest app ever  aodaliyar  1 star

I don’t know why I still check this app. It’s currently telling me my one year old should be helping with the dishes. Hahahahaha. Pretty sure whoever wrote this has never actually met a baby.


Absolutely Fantastic  VanessaUebergang  5 star

The app was easy to navigate, information is clearly communicated and laid out. App always worked! Such a helpful and invaluable parenting resource. Definitely 5 stars!


Wondering what’s happening with baby?  Lala-pixie  5 star

This app gives really good insight into what is happening with your Bub and what skills they are developing.


on point  mummabear35  5 star

Every time my baby is upset I read the leaps on this app and it help me help my baby through her storm clouds... also help me teach her new things

Harrison Jack's mum

Using this app for my second baby  Harrison Jack's mum  5 star

It was so good to be aware of when our baby went through a mental leap and what he might have felt/experienced. It helped us understand his world and be more empathic to our baby’s needs. I am now using the app for our second baby! I feel this time round I will be more prepared for the fussy phases and embrace it when it happens.


FTM says Thanks!  KylieS1  5 star

When things seem to be going tough, this app shows that bub is going through a leap and sunnier times are ahead! Thanks so much! Its helped me get through!


Helpful  Chezisthebest  5 star

Great app to help with understanding the developmental stages for our baby. It’s been a great guidance tool in understanding what to expect.


Sanity saver  crosswordfanatic  5 star

Knowing what’s happening is a sanity saver, the tips helped to much too.

Melinda S P

Biggest parent helper  Melinda S P  4 star

This app is fantastic. It has so much insight for parents with babies. I have watched this app for two children and it is spot on. It helps me develop my children’s learning and be relevant for them. I parent better because of it. Thanks for doing the research.


Great reminders  J-Bird415  5 star

Love the reminder that when my baby is fussy, she is probably doing so much growing that I’m not even really aware of. We used this app with our first and I’m so excited to be using it with our second.

Amy Brannock

This app doesn’t have help me at all  Amy Brannock  1 star

Unfortunately, this was a waste of money. The information is useless and does not align with my child at all.


Meh  EndymionNomad  2 star

I mean, I could’ve gotten all this app has to offer in an e-book. Really don’t see what the fuss is about. A LOT more apps out there have daily value. Pretty disappointed.


MUST HAVE! Great baby shower gift!  Sunshine1111  5 star

If you don’t yet have the Wonder Weeks app, I cannot recommend it enough. I used it for our 21mo, and it was so nice to know ahead of time when I could expect her to be fussy, grumpy, or clingy. I’m only 25 weeks, but I’ve already programmed baby’s due date (WW works off of due date, not birth date, which the app explains why), and the app has programmed baby’s leaps into my calendar. Normally I cringe at the thought of spending money on an app, but this did prove to be valuable enough, and worth the small expense. App works great, communicates with iPhone calendar, and even has instructional videos that are so helpful.


Not good for preemies  Ranman21  1 star

So the app specifically states to use due date because that is when baby will leap, and not when they were actually born in the case of preemies. This is wrong by my own observation with my preemie. It says she won’t have first leap for a little bit yet (she is 9 weeks tomorrow and came exactly 5 weeks early) but she has already gone through second leap. She plays with her hands by wringing them together. She waves her arms intentionally. She is making noises like “ah” and others. She is leaping at her age not her gestational age.


It Works! It’s True!  Jenthebeliever  5 star

Have found this app sooo helpful in understanding my daughter! It’s been spot on!


Must have for new parents  LilMonkeyXs2  5 star

The book is great but the app is even better. The calendar chart is very helpful. I was amazed, the first time around, at how spot on the fussy phases are and it’s the same with the second baby now. A little less stress when you know when the storm is coming in.


Completely in sync with my baby  LaurKess  5 star

I love this app because it helps explain what’s going on with my baby week by week, the good and the bad. It makes me more relaxed realizing that most of his behavior is typical of a baby at his age. Sometimes it’s freakishly on point with what my baby is doing that week. I highly recommend this to any anxious new parent like me!!


So Great!  BriHer422  5 star

Always pretty on point and gives me great insight into what is really going on in DD’s little head.


Useless  TiredMomOf6  1 star

All babies are different, and I should have known better than to buy an app that supposedly applies to all babies. The leaps might be skills that all babies learn, but there is no way of knowing WHEN your specific baby will develop those abilities, let alone when your baby will be fussy or go through a “stormy” period. It’s pretty absurd that the book and the app claim to give these predictive abilities to parents with a calendar. The “leaps” didn’t coincide at all with my baby. I followed the rules and went by my child’s due date, instead of birthdate, but still the calendar/chart was SO off base. My baby would have fussy growth spurts, and sleep regressions, during projected “happy” periods. And my child would master skills months sooner or later than was stated. This app is useless. I shouldn’t have wasted my money.


Fantastic App  COS_15  5 star

I love this app it really helps to know when your baby is entering a leap so that you can support them and understand them as they grow and develop. Love it!!


Love it  westcorkie  5 star

I'd be lost without this app. So many times I wonder, what's up with my baby and then look to find she's just entered a stormy period before a leap.


Excellent app  Sboppets  5 star

Used this with both my children an incredibly accurate. Highly recommend and for baby number 2 it gave me a great refresher to key milestones.


Great but can be slow  Mogsie  4 star

I find this app great for recording feeds sleeps nappy changes. I have no concept of time so this is a godsend for me. The only downside is that sometimes it freezes when you are trying to start/stop the timer and also when reviewing stats. Overall good though.


Would not recommend  Dazzer2015  1 star

Not impressed with this app. It only gives the bare amount of information and is really only a platform for advertising their book. Waste of money


Great app, small error  shoegalsteph  3 star

Great app, all Wonder Weeks info in one, easy to read place Weeks are numbered incorrectly however on the chart. The date is the same at the end of a row & beginning of the next but the weeks continue to increase.


Nonsense  Ms1183  1 star

Don't buy this app it's terrible. Makes no sense at all. Waste of money. Would give no stars if I could


Mrs  SummerTreasure  1 star

What a load of non-sense!


Great  Styleyouboi12  5 star

Found it a great app really very helpful love it :)


Dated  missdejamoo  1 star

App is very dated- information is nothing new. Also, don't like the way baby is always referred to he, not he or she at different times- again showing how dated it is.
