Redirecting

Before we found out my stepdad diagnosed with Alzheimer’s my mom would argue and fuss and get hateful and tell him to shut up and tell him that didn’t happen and that’s not true and of course he would smart back and fly off. Now I’m caregiver for both and she’s learning. Me and my stepdad have a wonderful relationship we have a connection because I listen and laugh and agree acknowledge him respect him don’t get angry. Now mom is learning more and being more understanding but even when she trying to do those things now he will still get mad and argue and think she being a smartellic and pop something back. Is there some other things she can do extra to show more love and understanding. I tell her things and she’s trying. Can you give me more examples to show love I have tried so many. I told her hope that’s not the last thing he remembers of you I’ll take any tips
