Letsquilt,
I am so very sorry that your dad is having to go into a home. My sister and I took care of both my mom and my dad when they were too old to stay on their own and in the end in their separate homes. They passed on two years apart.
It was very hard and sweet at the same time. I don't know if that makes any sense. It was just such a privilege to give back a little and that took the bite out of the circumstance, not out of the loss.
I found that the little things I did to spoil them while they were needy was the most precious to me now.
