OP here.....
My 9 year old figured out Santa, then the Easter Bunny, Tooth Fairy etc... She knows there are humans inside of the costumes already. That magic has left already.
When she asked me if we could go to Disney one more time as a "kid" it just made me think that Disney is a bit more special for a "kid" in her mind and she knows that will probably end at some point. Of course she is not aware that taking her kids years from now will provide just as much magic.....but I digress.
She still loves the princesses, meeting the characters, and getting lost in the magic of Disney. Maybe that will never go away as some posters have said. I just thought I want her to have that magical feeling one more time....before she is not a "kid" anymore.
