Awww, poor little sweetie!! When I get my grandsons in World of Disney, or any of the huge shops, they end up on overload. I think it is just too much stuff, too many choices and often a few too many 'no's', although they are pretty darn good at understanding 'pick one thing'.
She usually does pretty well not asking for things in real life, but at Disney it's another story. She knows that we'll spoil her there, and she goes a little crazy sometimes. I understand it, it's gotta be hard to be 5 and surrounded by things that you want.
It's hard though! I still remember on my first trip to
Disneyland YEARS, no eons ago. We were on POTC, on the second day it was open. We had absolutely no idea what to expect. We went down the big 'hill', it was dark and my Mary Poppins hat flew off. I cried so much, that my parents bought me a replacement, which was totally out of character for them.
It was funny, because on Wonderful World of Disney, they showed the POTC on a special they had, commemorating the opening and other park changes. Guess what? It was my family in the boat and whoosh, there went my Mary Poppins hat.
