Thankyou Stef
Yes it is a relief, although they are going to need to have someone there at all times now because Grandma can't take care of him by herself. My Grandpa can be a handfull and he is pretty stubborn as well. He will try to do things that the doc says not to and Grandma won't be able to stop him from doing it either.
My dad stayed with them last night to make sure that everything went ok, and my Aunt's are taking turns staying as well.
