The Wonder Weeks

The Wonder Weeks, a company of Dutch origin, wants to make parents feel confident when taking the biggest leap of their lives: having a baby! We are here for all parents and highlight the ups and downs of parenthood. Our book about the mental development of a baby, the 10 leaps in the first 20 months, is a worldwide bestseller for over 30 years! And with our app, available in 16 languages, we created a digital solution with over 77 games to play with your baby, a personalised leap chart and automatic notifications when a leap starts, so you will always be prepared! The Wonder Weeks is also known as Oei, ik groei! (Dutch) and Oje, ich wachse! (German).
