Trivia: The baby that laughs at the beginning of the movie and the little girl that Tinkerbell brings the lost toy at the end of movie is the same little girl. She is Wendy Darling from Pete Pan.
Suggested correction: Tinker Bell is born just before spring and then when spring arrives she brings the music box, so the baby can't be Wendy because it was only a few weeks at most.
If I'm correct, time in Neverland runs differently then on the main land.
