It might not be orginal, but my two year old has been obsessed with Mickey since she was about five months old *her first trip was at four months, hmm ...*
But no, each and every trip, we hit up Mickey in ToonTown. Somehow it's always ended up with just us and Mickey in the room by ourselves. The first time, Julie didn't really get it ... now she hugs and kisses him. Especially when she was tiny, I'd notice a difference each and every month, now she just looks old.
It's starting to happen with Cinderella as well. We can't walk past a princess out for pictures without Julie running over to them.
