No. The app is a short summary of the book. The app is a handy tool which calculates the leaps for you and let’s you know when your baby is in a leap, and it gives you a short summary of the leaps. It doesn’t contain all the information of the book.

We hope you can understand that we can’t make the entire book into an app.

Yes! We can’t say this often enough. Only knowing when there’s a leap is not enough!! You have to know what is going on inside your baby’s head in order to help him. Only using the chart is like saying: “Oh my baby is sick” but you don’t know what is making him sick and you don’t know the right treatment to make him better.
To calculate the leaps you have to enter the due date. Also with preemies and twins. The timing of the mental development of a baby is linked to the age since conception and not to the age since birth. Therefore, to know when your baby is making a leap, you have to fill in the due date, and not the date of birth. Look at it this way: the brain of a baby that is born three weeks early is not as far developed as the brain of a full term baby. The brain develops, in and outside the womb. This is why we calculate with the due date.
No, a leap is not the same as a growth spurt. A leap in the mental development of your baby means that suddenly there are many changes in his/her head. Suddenly, his/her brain perceives things it wasn’t capable of perceiving before. This change is so great that her entire world suddenly looks different.
There are definitely more leaps, but we haven’t written anything about those leaps. We do know that leaps will continue throughout your baby’s life. You can notice them by the three C’s. Also in the teenager period (think of puberty, that’s a big leap 🙂 but some things will change. Like the need for breastfeeding will be less and he doesn’t want to sit on your lap as much 🙂 But during the teenager periods he/she will be cranky and crying 🙂 We don’t know when all the other leaps will start and when they will end. Just remember what you’ve learned from The Wonder Weeks and adjust some things to his/her age. So don’t worry, you will know the signs! And remember: Only you know your child the best!
Yes that’s possible. The clingy periods come at 5, 8, 12, 19, 26, 37, 46, 55, 64 and 75 weeks. The onsets may vary by a week or two, but you can be sure of their occurrence.
