I don't know whether to chuckle or really think about this. The one that seems obvious to me is Eeyore who's sad all the time. Christopher Robin having schizophrenia - that's pushing it and its fictional /make believe. The characters need to be interesting with opposites to other characters to make an interesting read. If they were all the same it would be boring.
One thing I do agree with - isn't good to teach little girls to live the Princess way of thinking - eg. 'waiting for a knight in shining armor to rescue them' etc. Thank you for sharing this and it was interesting to read.
