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


Must Have Parenting App!  JediJenn90  5 star

This app was a life-saver during the first 1.5 year of my baby’s life! When she was fussy for apparently no reason, we had something to turn to. It’s so hard seeing your baby be cranky! But not knowing what’s going on or how you can help makes it so much worse! This app will let you know when your child will be going through mental leaps based on their age. Leaps in development can also mean fussier periods. It’s also super fun to look out for and notice the changes that the app says should be happening! This app was spot on for my kid and I’m so glad I had it!


Definitely a smart app to have  AshlynnsMommy  5 star

I was suggested this app from a lovely mom friend I have who swore by it and i can’t even tell you how accurate it is and how relieving it is to be wondering about what’s going on with my child and see that’s it’s normal! Very much so worth the money to get this and wish I had/knew about it with my first!

Beautiful Design

Best newborn parenting app!  Beautiful Design  5 star

The Wonder Weeks app is so easy to use, gives reassurance during Baby’s fussy phases and it’s fun to see what Baby is learning right now. If you haven’t read the book, it’s a fun read, but this is easier for new parents for sure!


Great tool  LeezerRN  5 star

New parents! You need this app. It’s worth the $3. Reading up on why your kiddo gets irritable or fussy helps you understand what’s going on in their brains, therefore making these stages less exhausting and frustrating! Well set up with bullet points, videos etc that all help make this info easy to digest when sleep deprived and busy with a little one. Love the alerts that connect to your phone so you know when they’re about to enter a new leap!


Not all it’s cracked up to be  FlyingAnnie  1 star

Worst $2.99 I’ve spent. It only gives you about 5 sentences on why your baby will cry in the next 3-5 weeks and how to soothe them. That’s about it. Not user friendly and you can’t read future leaps. Our baby seems one leap ahead of what the app says but we can’t view the next one in advance. We adopted our baby and mom didn’t receive prenatal care so we don’t know when due date actually was. So it’s a pretty useless app for us. Not sure why so many people love this app so much.


Worth the money  Rkcmommy  5 star

I was hesitant to purchase this app at first, but finally did after several friends swore by it. So far it has been spot on with my son and his fussy periods. It helps keep you sane as a parent because you know when to expect a fussier/clingier baby & it offers helpful suggestions and insight. With my first, I always thought it was something I was doing wrong. Now I know that these are leaps that all babies go through! Love this app!


Love loveeee this app!  DeDe812  5 star

Absolutely love this app! It has helped me so much with not one but both of my babies. One is 18 months old and my other is 1.5 months old.. highly recommend this app to everybody who has babies or toddlers!!!


Freezes up phone  Rolls20  3 star

Great information and super helpful, but every time I go to open the app it freezes up my phone and sometimes the app won’t even work. I’ve had to do a hard restart several times before because I couldn’t get my phone to respond after opening the app.


Paid reviewers?  Daverunner1002  1 star

I don’t know whether the other reviewers have been paid, but I don’t know how else a higher rating than horrible could be attained. I’m short, this app is a complete waste of your time.


A “MUST HAVE” App  MJRnVnE  5 star

I’ve now used this app with two of my children...I wish I had known about it for the first two! Because of this app, I was aware of WHY my babies were crying, fussy, restless through the night, and needing more attention! It took so much guesswork out of a time that can be very frustrating! This is a MUST HAVE APP for any parent, new or seasoned!!


A bit confusing.  Cute2883  2 star

I put my daughters due date into the app, so it knew she was 5 months old, but some of the things it says do not match her age. For example it said something like ‘talk to your baby. Ask if she wants a sandwich while you’re setting her place at the table’ and ‘play with your baby on the floor, letting them crawl back and forth to you’. She’s 5 months old! Not crawling around eating a sanga just yet. Know I’m not sure which parts to trust.


So good!  rebecca.munk  5 star

I love to see the next leap and what development my bubba might be in for.


I dont see any good thing about this  hajshshaj  1 star

Its an ok app but should be free for what it is theres not much in it and the videos doesnt play. only one video played the first one about the change of her voice the rest of the videos ate black. not playing.. disappointed about this app


Spot on  TobynKarms  5 star

Love this app so much, it has helped me and my husband gain a greater understanding of our son’s mental development and all the changes he his experiences. This app is making it easier for us to support him through his leaps Thankyou.


Very Helpful  MeagsPahl  5 star

Although all babies are different, this app is very helpful to understand the development process babies go through at different ages


Not worth it  qeertyuiookngva  2 star

I don’t think this app is worth the money, it doesn’t really tell me anything useful it’s very fluffy and not detailed enough with specific leaps and milestones. It’s also not well designed.


Useful to know what to expect; don’t take too literally  AndreaKW  4 star

Sometimes our babies behave strangely and once a physical cause has been ruled out, it can be oddly reassuring to know that it could be that a whole lot of overwhelming activity is going on in their little brains. This is what I find great about the Wonder Weeks app and book - and offers an explanation and often it’s description i’d behaviours is accurate. Babies can be fussy during the leaps but once they’re over, or even before, they know how to do new things that amaze us. Just remember all babies are different so don’t take the information in the app too literally. Also, not sure if it’s things getting lost in translation but some of the descriptions and examples in the app are downright bizarre. Ie ‘your baby may be fascinated by a vomiting dog’.


So good!  BenicioMurray  5 star

This app has been such a great help with demystifying the scary unknowns of a developing baby.


Puts you at ease  Curiousath  5 star

Have used for both children and whenever I’ve noticed a change in their behaviour it’s always been spot on that it’s a leap (or a tooth to be fair...). The information and suggestions really put your mind at ease and help you to get through the stage as happily as possible.


BEST INVESTMENT EVER  ActivatingAbundance  5 star

This app has been absolutely priceless. I am a second time Mum with an 8 year gap and I seriously wish I had this app the first time around. It takes away the guess work, has helped me to be interactive with my baby based on the abilities I learn about in the app and has been a sanity saver when she’s been extra clingy, grumpy and waking frequently... because I can see she is in a leap and even be prepared for them! HIGHLY RECOMMEND! I also have the book and journal and have loved them all.


Spot on  Lindsaypaige9311  5 star



So helpful!  paldavsav  5 star

I love having the wonder weeks app available on my phone so that when my baby starts having trouble sleeping or acting fussy, I can check to see if it’s possibly a leap. It’s a good way to keep up with how baby is developing and what to expect.


A NECESSITY!!!  desbonafide  5 star

This app will assure you when baby goes into thru developmental leaps!! It has ways to help comfort baby, how to help during the leaps, what ever leap consist of and days baby will be happy/fussy. If you are a first time mom, shoot, maybe even a mom in general, this app is a must have!!


In the know  Lillian'sMom  5 star

It’s so helpful to know when my baby is going through a leap and what I can do to help her. There’s no wondering why she’s fussy or what to do to stimulate her. Wonder Weeks has been extremely helpful!


Cool info, but not accurate for us  ARC2755  2 star

I think my baby goes thru some of these milestones, and it’s fun to read about. I don’t think the timeline is at all accurate for my baby though.


Must Have!  Anniebby89  5 star

This app has been amazing so far! I can now understand where my baby is in his developmental level. I know ahead of times when he’ll go through a leap and how he’s slowly learning about the world. As a first time mom, I had no idea what was going on. I’m glad this app has helped me get through some rough patches.


Bible for 1st Time Parents  BrandiElise  5 star

This app is so helpful!! Prepares and equips you for all the newborn changes.


Helped me be a better parent  bytesizeanna  5 star

This app, paired with the book, in an incredible asset for parents. It enabled me to understand why our baby goes through challenging times —their brains are developing! I would recommend this app and book for every parent. I especially appreciate the notifications about when a “leap” is approaching.

Kait Myers

Best app ever!  Kait Myers  5 star

Love this app! It has helped us to know what to expect for our baby. Parenting is exhausting enough, but when your baby is fussy and you don't know why it can be very stressful. Especially if nursing, you start to think you are doing something wrong! This app shows you why they are fussy and even gives you ways to help them through those fussy times. It's like an angel sent from God! 😂🙌🏻


Love this app  JnHomer  5 star

This app is so helpful and always on point with her leaps and mood phases.


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 :)


Every parent should know about the Wonder Weeks  ClairMaria  5 star

Very helpful to know when your baby will be more fussy than usual. It’s also nice to know how they are developing mentally and how you can work on developing the new skills they are trying to master.


Double charged  Heylady_*  1 star

Why was I charged another R49 for an update?????!!!!!!
