CindyJanet,
We just came home from China in November with my sister's beautiful new baby (she named her Olivia!!) What a great experience. We only had 5 days notice before travelling so I can imagine how stressed you must be. Are you taking your Olivia? If not, I'm sure that it is killing you that you will not be home for Christmas. I can't imagine a better present for her though, than a new baby sister.
I hope you have a wonderful trip and that all goes well. Good luck and Congratulations!
