I wonder how old the LW's kid is. My five-year-old still occasionally tells stories about something that happened to other people or in a book as though it happened to them, like saying "I fell off my bike and scraped my knee" even though they don't own a bike and their knee isn't scraped. It's just part of being too young to fully grasp the parameters of reality.

But I balk at the LW saying "try to get my son to eat something" because if he's old enough to talk, he's old enough to decide what's food for him and what's not. A friend's kid only eats Nutella on bread. (I am not exaggerating. My friend goes around with a loaf of sliced bread and a jar of Nutella in her bag like most parents carry Goldfish crackers or Cheerios.) It's not ideal, but he gets enough calories to live on, and it's a lot less stressful for everyone if his parents roll with it. The LW can roll with her kid being a picky eater and stop trying to get him to eat things he doesn't want to eat.
