We are flying out from NYC to Cali next Thursday so DD can meet her great grandma (my dads mother) and I am getting nervous about sleep with the 3 hour time difference. Cali is 3 hours behind NY and we are flying out at 715a which means we have to wake DD and head out to the airport at 445a (yea I should have planned this better sigh). So I'm already waking DD 2 hours before her usual wake up, and we arrive in Cali at 1130 PST. I'm worried about the time change and how DD may crash on the first day from everything. Plus we are only there for 6 days.

Should I be making any changes to her nap/bedtime now to prepare for the trip? When we get there, should I do her schedule based on PST, EST, or just read her cues? Any tips for helping them deal with this change?
