I'm also pleased to hear your news Katek, it must be a weight off your mind, it's so hard for those of us that don't deal with this day in and day out to know what is the best thing to do. The doctors have removed that worry from you now so you can concentrate on being there for your MiL when she, and the rest of the family, need you. As HildaW has said, this posting from you does sound much calmer, you sounded so stressed in your other postings (which is understandable).
That is such a lovely offer from your GD, what a kind, caring person she is - you must be very proud of her.
