Billie,
Keep up with the soups, hot teas, broth and Vitamin C
Might be best to wait until they all arrive before getting a new place - they would probably like to help pick it out.
And the schools will need to be checked out for the daughter.
It is fun to look isn't it? - you can send them pictures and links to the ones you like.
I've been looking for a place for one of our boys to buy around here- i love the websites that have lots of photos or the virtual tours.
Have you spoken or IM'd with his daughter and mother too?
