I'm so sorry, Chris I know what a sad and disappointing time this must be for you and DH.
I don't know much about adopting, but do you have to tell them about the MS? You take a chance too, you know, as the new Baby may have a genetic possibility for illness.....Maybe even MS.
I hope an Adoption is a probability for you and the process all runs smoothly. A lot of People become Parents and don't want it...You want to be Parents, which is a plus in my book.
Again, I am sorry for your loss and wish you better roads ahead.
Love,
