After learning that reasoning with my father was pretty futile, he would argue the most simple requests, change clothes, take a shower, etc.. My father always had a sweet tooth and I learned that if I threw a “after you take a shower dessert will be served” or “after you change I have some candy for you”. This worked like a charm. I would have stashes of sugar free ice cream or candy ready to go. Most of the time he would forget that I had said that after he had done the task. It also came in very handy if he was getting agitated with the children playing or if he was caught in a question loop. Having a distraction ready to go for him is essential in dealing with those moments. He could be extremely upset that the baby was listening to his instruction, within five minutes of me distracting him with a treat he would forget what he was frustrated with. The only problem was that I had to then deal with little kids saying “what about me”. Not wanting them to learn that negative behavior was rewarded with candy was a bit difficult but we were very consistent with explaining that their Papa sometimes gets confused and that the candy helps. Raising kids in the house has been a bit challenging. My father is very found of children but is more like an older sibling that a grandfather. They have grown to understand and are our little helpers and as they have grown older and he has slipped more they have been able to assist even beter.
