John, My husband will do that on occasion -- just take a couple of bites and refuse anymore. Especially at night he doesn't want much but I don't make an issue out of it because he will get it firmly entrenched in his mind that he doesn't want anything to eat. I just say ok and about an hour later I will ask him if he wants some dessert which he always does!
At this point I will not press him to eat however I leave his plate on the table while I finish my meal. Sometimes he will forget and start to eat but not often. Good luck!

My husband does this too. He never turns down ice cream even when he didn't want any dinner. And I just think, why not.

Also, I had gotten a Alzheimer's clock from Amazon for my Grandmother and all..it helps most days. 🙂

Thanks
