I'll pray and light a candle for them. This same thing happened to us- we could have finalized in June but we were waiting for ONE SHEET OF PAPER from the state- the paperwork was approved and finished, they just needed to send the physical copy to our agency. Then, by the time we got it, our judge went on maternity leave and the judge covering for her is notorious for delaying or denying adoptions for silly reasons, so we decided our best bet not to deal with the covering judge at all and wait for the boys' regular judge to return- that put us to August 7th.
I am sorry to hear about your husband's grandfather. I hope this will be a comfort to you- my grandfather (my mom's dad) married my grandmother at 17 and also had never been on his own. We had said for many years that we thought if grandpa went first, grandma would be okay, but we could never imagine grandpa making it without grandma. Besides the fact they were so overwhelmingly in love, grandpa didn't even cook, do laundry, or any of those things for himself. Well, grandma passed away over three years ago and I'm happy to say grandpa IS doing it, and seems to be relatively happy, to boot! I will pray you all not only find peace, but that grandma finds comfort and strength on her own!
Best of luck finding a sitter. I have watched my nephew (and niece during summers) for 2 and a half years, but did tell them that I will have to stop this fall. Five kids is just enough on it's own, and the kids all have special needs of one type or another. I love kids- but I love my sanity too! But at least this is a good time of year to search for a sitter, as many will have been working for families where all the kids will now be in school in the fall and will most likely need a new position!
