I am so sorry Mindi I think the help you are giving looking after your DGD is beyond price. Going by my experience with DH's cancer (with both children grown up) I think anything you can do that will let your DD concentrate on her husband while you try to keep a semblance of normality for your DGD and keep an eye on the pregnancy will be so valuable.
I wish I could offer more than sympathy, but I hope you can find the strength to get though this. 
The Salt Path - what do you think?
