My husband is 90 and has MID, a form of dementia and he is rapidly declining. I am 70, we have been married 45 years. I have always gotten along well with the step children and do not understand how they are not responding to his obvious (to me) needs for interaction and support from them. They call and ask how he is but do not spend time with him.. I have physical limitations but he is still physically healthy and exercises every day! How do I approach the kids? I don't want to make them feel guilty but I think they should be made aware. I don't know what to do.
