Hi! First of all thank you for such an interesting task to work on! I done few screens to display the idea how I imagine this app to be. The design is clean and simple with some "playful" colored elements to keep the "kids" theme. Main focus was on creating an intuitive, fast to use UX, which I think is accomplished here pretty well. I also made a short video for display interactions and for have a better feeling of the end product.
