Thank you for sharing this experience of your family, it is really magical to watch the movie with children and to be able to talk about that, to discuss something and sometimes you find that you also may change your opinion as sometimes the children may have their own interpretation and you never thought about that. The books with Winnie the Pooh were first that my son started to learn reading and I remember how on and off we read them until he could fluently read, but I did not realized that was only his photographic memory for the words and text so he knew it by heart. I thought that he was really easy ready but he was telling me by heart. When I realized that we anyway had a lot of fun, as that is another very good skill that children can develop while little and to bring it to perfect with years.
Until now those books are his favorite, I have not heard about the movie but I think we will also have a fund watching it :)
