Either way, but to me, letting them remember her the way she was would be best. I am 64, we lost my mom last year. She lived in an apt on to our house. My daughter and her little girls were here all of the time, and the girls went in to see, "Grammy " everytime they were here. One night, mom just keeled over, and we found her later. We told the girls that Grammy had died, and she was in heaven, and she could run around and see her dogs and my dad. Just the other day, out of the clear blue, the 31/2 yr old said, "was that like Grammy" I said, our Grammy is in heaven, remember? And she said, " yes, Grammy is in heaven". So, there is not much memory and as long as it is not horrible, it will be ok. The thing is, is your hubby better off there, without having to worry about the children, or would the children be good for his dad, or just another problem. The end is very sad, it is awaiting game, you don't know when, she is requieing a lot of physical care. If she hears, have the children talk to her on the phone, that is enough. Have everyone tell her you love her. Tell the children she is very sick, sometimes people get that way when they get old. There are good books for children at Barnes and Noble. God bless, this is a hard time for you.
