Thanks for the input-this sounds really stupid, but I hadn't really thought about what the 7 hour time difference would be like for my daughter. I think grandpa would love to see her, but maybe it's selfish to impose what's sure to be a nasty case of jetlag on a her just because I'd like to see them together.
We have decided to see whether or not we can extend the visit to see other relatives (and stay for two weeks total), and if not to probably leave her home with Papi (who is completely capable of taking care of her for a few days

).
