I saw in the Birth Month check in someone mentioned their daughters favourite princess. It makes me wonder, what is your son/daughters favourite Disney character and have the seen the movie with that character?
Natalie changes her mind a lot, though she does favour the princesses over other characters. I'd say her favourite is Princess Aurora, yes she's seen Sleeping Beauty, I think she likes the Aurora most cause her dress is pink. Natalie has several puzzles with princesses on them and can name every one.
I gave some of Dana's old Barbies to Natalie a couple of days ago, some Disney Characters, and she really likes the Beast, even wanted to sleep with him last night, I don't allow hard toys in bed so he sat on her toy chest all night and then traveled around the house with her this morning before she went to school.
