For Christmas I bought my 4 yr old DD the sing along tape called 'Beach Party at WDW' to get her used to seeing the characters. Recently I bought the sing along tape called 'It's a small world'. Now my 7 yr old DD is questioning if the characters are real or just actors. She came to the conclusion that they must be actors in costume because their months don't move. Here's my delemna, do I tell her she's right but ask her not to tell her sister or do I deny it? I don't want my 4 yr old to lose the magic. This is the first trip for them. I did warn them that the characters can't talk to them like they do on the tape. Help.
