About this app

The world’s No. 1 baby app! Understand why your baby cries more at certain times, isn't himself or herself and... what you can do to help.

During our research, which began in 1971 with Jane Goodall and the chimpanzees in Tanzania, we discovered that babies are more prone to cry and to be clingy or cranky from time to time. This behavior was shown to be related to a developmental leap in the baby's mental development. More specifically, babies go through 10 developmental leaps in the first 20 months of their life. A leap may be tough, but it's a positive thing: it gives your baby the opportunity to learn something new.

Use The Wonder Weeks app to:
- See when a developmental leap starts and ends thanks to a personalized leap schedule
- Be automatically notified when a leap is about to start
- Learn to recognize the leaps based on the various signals your baby gives
- Discover the new skills your baby develops with each leap and reaches important baby milestones
- Stimulate your baby's new skills with 77 playtime games
- Keep track of your baby's development in your personal diary
- Link the app to your partner's app to keep track of your baby's development together
- Share your experiences and ask questions in the forum
- Watch fun and interesting videos about parenting

Our mission is to help parents gain confidence in the face of the greatest leap in life: having a baby. We take a candid look at parenting, shed light on all sides and are there for all parents. We can all help each other and learn from each other.

Millions of parents before you have already followed, supported and stimulated the 10 developmental leaps in the development of their babies. It's not a coincidence that we have been one of the best-selling baby apps worldwide for many years!

L'application pour bébé n°1 au monde ! Comprenez pourquoi votre bébé pleure plus à certains moments, n'est pas lui-même ou elle-même et... ce que vous pouvez faire pour l'aider.

Au cours de nos recherches, qui ont commencé en 1971 avec Jane Goodall et les chimpanzés en Tanzanie, nous avons découvert que les bébés sont plus enclins à pleurer et à être collants ou grincheux pendant certaines périodes. Ce comportement s'est avéré être lié à un bond dans le développement mental du bébé. Plus précisément, les bébés traversent 10 bonds mentaux au cours des 20 premiers mois de leur vie. Un bond peut être difficile, mais c'est une chose positive : il donne à votre bébé l'opportunité d'apprendre quelque chose de nouveau.

Utilisez l'application Les Semaines miracle pour :
- Voir quand un bond commence et se termine grâce à un calendrier de bonds personnalisé
- Être automatiquement notifié quand un bond est sur le point de commencer
- Apprendre à reconnaître les bonds en fonction des différents signaux que votre bébé donne
- Découvrir les nouvelles compétences que votre bébé développe à chaque bond
- Stimuler les nouvelles compétences de votre bébé avec 77 jeux de société
- Suivre le développement de votre bébé dans votre journal personnel
- Lier l'application à celle de votre partenaire pour suivre ensemble le développement de votre bébé
- Partager vos expériences et poser des questions sur le forum
- Regarder des vidéos amusantes et intéressantes sur la parentalité

Notre mission est d'aider les parents à prendre confiance face au plus grand bond de la vie: avoir un bébé. Nous regardons la parentalité en face, nous éclairons tous les aspects et nous sommes là pour tous les parents. Nous pouvons tous nous aider et apprendre les uns des autres.

Used this app with my first 2 kids and it was such an amazing help. I'm expecting my 3rd baby soon and knew I wanted to use it again. I'm disappointed to find out it's a paid subscription now. I understand needing to make money to support what you created, but simply adding an ad or two, or giving an option to have a free version of the app would have been better than cutting off complete access behind a paywall.

I already paid for your book and now you're telling me I have to pay a premium fee to access all of the information in the app?? If you don't subscribe you don't get all of the information and the app doesn't function completely for you. I'm not interested in paying for your content twice... I'll stick with the book I already own. Uninstalling. I get paying for premium app content and would do that but the app doesn't even offer full basic functions without pay. Not one feature fully works w/o $

The app and the book are 2 separate and unique products that complement each other well with the theme of leaps. The app is a complement to the book and makes itself user-friendly, but there are also more possibilities in the app that are missing in the book, you can add photos and notes and much more.

I like the info but IMO there is no reason this should be a subscription model and DEFINITELY not one as expensive as this when we're just interacting with information published in a $10 book. I paid for 3 months one time but decided to cancel and not financially support such a greedy model. I would absolutely have paid a one time cost and now rather than also buying the book I think I will forego the information entirely. If there's a reason for subscription it needs to be transparent.
