The Wonder Weeks App Review: Your Baby’s Growth Just Got Easier
What’s Going On With My Baby?
Ever wondered why your calm, sleepy newborn suddenly becomes clingy, cranky, or cries for no obvious reason? Parents call it “wonder weeks” for a reason. Babies go through rapid mental growth spurts—also called leaps—that temporarily shake up their world.
Here’s the thing: those leaps are actually a sign your little one is learning new skills, perceiving new sensations, and making big cognitive jumps. But while your baby is figuring it all out, you’re left guessing… until now.
That’s where The Wonder Weeks app steps in like a trusted friend.
So, What Is The Wonder Weeks App?
The Wonder Weeks app is based on the best-selling book The Wonder Weeks by Dutch authors Frans Plooij and Hetty van de Rijt. It takes decades of baby development research and wraps it into something super practical for exhausted parents.
Instead of generic advice, the app tells you exactly when your baby is going through a leap, what’s changing in their brain, and what you can do to support them. It’s like a personalized timeline of your baby’s mental development.
No more wondering if the clingy phase will ever end—you’ll know why it’s happening and when it’ll ease up.

Why Parents Love It: A Quick Snapshot
- Personalized Leap Calendar – based on your baby’s due date, not birth date (because development follows gestational age).
- Clear Explanations – each leap explained in plain language with relatable examples.
- Practical Tips – activities and ways to stimulate your baby’s new skills.
- Fussiness Forecast – a handy chart shows when your baby might be fussier.
- Milestone Tracker – record first smiles, rolls, and words as they come.
And yes, it’s available on both iOS and Android, so no one’s left out.
How It Works: A Parent-Friendly Guide
Let’s keep it simple:
- Enter your baby’s due date
- This is key. Even if your baby arrived early or late, the app calculates leaps based on the expected date, which aligns with brain development.
- See the leap timeline
- A colorful chart shows the 10 major mental leaps in the first 20 months. Think of it like a roadmap of your baby’s brain growth.
- Get notified before a leap starts
- You’ll receive a heads-up that fussiness might be coming. Parents call this a lifesaver for their sanity.
- Learn what’s happening
- Each leap has detailed info: what your baby is perceiving differently, what skills they might start practicing, and why they’re extra clingy.
- Try suggested activities
- The app gives fun, simple ideas (like peekaboo, tummy time tweaks, or songs) to nurture your baby’s new skills.
- Track milestones and memories
- You can log special moments with photos and notes, turning the app into a mini baby journal.
It’s not just about fussiness—it’s about understanding your baby better.
What Makes The Wonder Weeks App Stand Out?
Honestly, there are loads of parenting apps, but few feel this spot on. Here’s why it hits home for so many parents:
- Science-backed but easy to read
- It’s grounded in 35+ years of developmental psychology, yet it doesn’t feel like reading a textbook.
- Predictive, not reactive
- Instead of scrambling during a crying storm, you’ll already know, “Ah, Leap 4 is here. It’ll pass soon.”
- Relatable for first-time parents
- Parents say it feels like having a wise grandma mixed with a child development expert right in your pocket.
- Helps you empathize
- It reframes fussiness as progress, not “bad behavior.” That perspective shift is priceless on sleepless nights.
A Closer Look At Key Features
- Leap Countdown
- A visual timeline counting down the days until the next leap begins (and ends).
- Fussiness Chart
- Shows sunny weeks (easy days), cloudy weeks (mild fuss), and stormy weeks (major clinginess).
- Skill Highlights
- For example, Leap 3 (“Smooth Transitions”) means your baby starts noticing smoother movements and transitions—hello, new visual depth!
- Activity Ideas
- Simple games tailored to each leap to support new neural connections.
- Milestone Journal
- Add notes, pictures, and keep track of key achievements like rolling over or babbling “mama.”
It’s like having a growth diary without any guesswork.
Pricing
The Wonder Weeks app is a one-time purchase:
- $4.99 (iOS & Android) for lifetime access to leap predictions, mental development insights, and personalized tips.
- No hidden subscriptions or extra fees—once you buy it, that’s it.
- Optional add-ons (like e-books or audiobooks) are available for parents who want even deeper guidance, but they’re not required.
For the cost of a single coffee, you get months of reassurance and practical advice during those intense early parenting days.
Real Parents, Real Talk
“The leap alerts saved my sanity. I stopped blaming myself for every meltdown.” – Jessica, mom of twins
“I loved the activity suggestions. It made tummy time actually fun for both of us!” – Omar, first-time dad

My Personal Take
When I first became a parent, I couldn’t figure out why my baby was suddenly cranky after being calm for weeks. The Wonder Weeks app felt like a reassuring friend whispering, “Hey, it’s a leap week—totally normal.”
I loved how it didn’t just say what was happening but explained why. The daily tips were short enough to read with one hand while holding my baby in the other. Plus, the countdown to the next leap gave me something to prepare for.
What really stood out? The journal feature. I could jot down little notes about my baby’s new tricks—like suddenly discovering her hands—and look back to see just how fast she was growing. It honestly made me feel less anxious and more present.
How It Compares To Similar Apps
You might be wondering, “Why not just use a generic baby tracker?”
Here’s the thing: apps like Huckleberry are amazing for sleep and feeding logs. But The Wonder Weeks is laser-focused on cognitive and emotional growth. It’s more like a developmental coach than a scheduler.
And compared to parenting blogs or Google searches, the app removes guesswork. No endless scrolling through conflicting advice—it’s all in one trusted place.
Is It Worth It?
If you’re in the trenches of babyhood, absolutely. For the price of a coffee or two, you get peace of mind for nearly two years. Parents say it helps them feel prepared, supported, and less overwhelmed.
Think of it as a cheat sheet for parenting’s most confusing months.
