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

Drey Reynolds

Best app  Drey Reynolds  5 star

This is by far the best app! A must if you have a baby! The weeks when the baby is taking leaps are right on and the helpful tips when they are going threw a leap! I love how you can have more then one baby on there at a time as well! Best 3 dollars I have ever spent!


Won’t update  my2pirates  2 star

There is a new version that wants you to pay more money and now this app will not update. Not happy at all. I paid for an app that won’t work now.


Don’t bother - read book instead  mama_dre  2 star

App is full of summaries - not worth $3 in my option. Let the full book instead.

Rachelle D5000

Confusing and poorly written.  Rachelle D5000  2 star

I regret spending money on it. I think that if the developers spent more time making it more user friendly, and also not having these giant chunks of information rather than having easier to read, short paragraphs, it would be greatly improved .


Was awesome until recent update  Rockywind14  1 star

Like most other reviews, I LOVED this app until the last update which requires you to pay for full summaries. These full summaries used to be included with the price of the app; however, now the developers seemed to change it to find ways to make more money by asking you to buy the ebook or audiobook for the full summary. I used to give it 5 stars, but now I want my money back after this change. :( Update - the developers have replied to my request denying any changes occurred even after I provided them evidence of paid content previously being removed. Poor customer service.


An Essential Baby App  Rater4  5 star

Especially when the child is your first, like ours, this little app is like having a pocket manual for your baby. It is especially useful when little one becomes inexplicably fussier. Why? Well, according to the Wonder Weeks (which is based on evidence-based medical science), this is usually because your child is going through one of the many ‘leaps’ of childhood. The app was incredibly accurate in predicting when (indicated by a rain cloud icon) our sweet one suddenly because much more sour. Knowing this was itself helpful since parents armed with this knowledge can fortify their emotional defenses in preparation. While some baby apps are fun - but do little in the way of informing parents - The Wonder Weeks stands out as the rare outlier which both satisfies our curiosity while respecting that our time for doing so is quite limited after baby’s arrival. I highly recommend it.


Not worth it  LS763  1 star

The only thing you will use in this app is the calendar and you can make one yourself if you really want to. The home page information is confusing because it tells you briefly about the upcoming leap but somehow by the end of the blurb you realize it’s talking about the last leap. You have to go into the “all leaps” section each time to read about the one that’s coming but even that is annoying because they are labeled by the number of weeks your kid will be at he end of it. I just want to read about the 5th leap not the Leap of the 26th week. Besides my kid is not going through these on time anyway so it’s not even relevant. Oh yeah and the videos don’t work.


Hidden Costs  Moostng  3 star

You buy the app for the information but then have to buy the chapters too. Same the money - and just buy the book if interested. Kind of an expensive app for additional purchases. There is some interesting information but I’d rather put my $2.99 towards a fuller information source.

Erin Coster

Makes parenting so much easier!  Erin Coster  5 star

It’s so much easier for me to handle my fussy baby when I know why he’s fussy. There’s not always a lot that I can do about it, but it gives me a little added patience knowing he’s going through a huge chunk of development and that’s the reason for his behavior. I can’t say enough good things about this app!


Good App, pointless if reading the book  princesskiersten  3 star

The app itself is pretty good, but it lacked a lot of information. I found that I don’t use it and don’t get any new info out of it since I have the book. If I didn’t have the book the app would be fine. I wish the info in the app was either additional info to the book or more practical. I feel like I wasted my money on the app.


Absolutely spot on!  sarah.renee  5 star

This app has been amazing! It has been so helpful to myself and my husband, to help understand what’s going on in our daughters little brain. It has been spot on since day 1, to the day. I have been recommending it to anyone with a new bub, it has helped us a lot and is fascinating!


Disappointed  Amanda1s1  3 star

I paid for this very average app , upgraded my iPhone and it’s the only thing that just will not upload from my iCloud back up Also it’s obviously saying things happen at the absolute latest possible time because my twins born early and my niece born right on time are all so far ahead of this app it’s pointless looking at anyway. Honestly just want it to download on my new phone out of principle!


Third baby, still learning!  FelEagle  5 star

There has been a lot miscommunication which leads to a lot of screaming from my 11 week old, but this app has helped so much! Third baby and I’m just finding out about phases and leaps, not sure how my first two kids survived! Anyway definitely worth a look for all mums.

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!


Love it  Luna1818  5 star

So on point with everything that’s happening to my little one!


Love this app!  S_ram  5 star

This has been so accurate and helpful. My baby is 12 weeks and this has been a lifesaver!

Lauren C E

⭐️⭐️⭐️⭐️⭐️  Lauren C E  5 star

We found it very informative as to when our daughter would be going through fussy stages. The App outlines new leaps babies go through and the comparable guide to cognitive and physical abilities that are a part of the stage. So far, it’s spot on with our little one! Great app. I would highly recommend to anyone with a newborn. My sis in law recommended my husband and me to buy!


Disappointed  Brit-nic  2 star

When I first had my daughter everyone raved about this app so I gave in and got it. I followed the directions and went off babies due date and not birthday. Well so far every single leap has been off. We have been through 3 leaps so far and every time she has had them at the time that would line up with her birthdate and NOT her due date. The more I have spoken with other moms of early babies they have told me their little ones didn’t match up either. I still keep the app to see what the next leap includes but I take the predictions on cloudy and sunny days with a huge grain of salt.


Couldn’t do without it!  mountain_mama  5 star

My son was born premature and this app has been so helpful and exactly spot on with his dev based upon his due date versus his birth date.


Amazing  KittySmalls1988  5 star

It is amazing how accurate this is. This is my second kid and was a little skeptical because I didn’t notice these things before. Now I know what to look for and it is spot on! I am much more prepared.


Very accurate  CAyed  5 star

I like how when my child is extra fussy I check the app, and he’s definitely going through a leap. As he grew I could tell when he was going though one but this app has helped me know the differences!


Great info, bad app  green_and_pink  1 star

The Wonder Weeks is great and I was loving that the app is more accessible than the book. However, the app keeps crashing and often it won’t open at all. Disappointed since the redesign


Exceptional info  Pinkraeja  5 star

The wonder weeks app has been incredible when we are feeling like terrible parents. It has been so reassuring that we are doing things fine and our little Man is just growing. The info has been spot on as the weeks have gone on! I’ll definitely be using this for the next little one!


Great app for busy Moms  JewelsBrake  4 star

This is a great app but if I had one complaint it would be that there is not enough reading material on each leap.


Would not recommend  NMoy84  1 star

This app is very disappointing. Twice now I’ve lost my notes where I recorded all my sons milestones. Last night my phone was updating and it restored the whole app to factory settings (none of my other apps do this when I update) so lost all of the notes again. The rating system in app will also only allow you to give it 5 stars or you can’t rate it at all! Absolute joke. Don’t waste your time.


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 :)
