Good unconverted e-book for young children

Dei e-book version of this classic children's book is nicely done. It contains all the images of the printed book. The text will be read by a pleasant voice. For the little ones there in the pictures simple animations. For the slightly larger, there are three little games. Our son (2 years) Experienced both the paper version as well as the e-book (with a parent) will be happy to, which he does not want to look further at the moment at the point at which lost the little polar bear, since it this turn of history does not find beautiful. We hope that he soon learns, however, that the separation is not permanent and it also transmits on daily life, because he clings currently very strong when a parent needs to get away.
Conclusion: A good complement or even a good substitute for the printed book, as desired.
One point deduction, because we have a multilingual version (our son is growing as many children nowadays bilingual) would wish.
