I do have a kid. We give our son a variety of foods and let him decide what he wants to eat. He eats a lot of different kinds of foods (big fan of Indian food atm), and the foods he wants to eat change from one day to the next. Treats are reserved for special occasions, mostly because those in particular can have a pretty significant impact on brain chemistry.
Forcing kids to eat is very well known to be a very bad idea.
This is just taking a very antagonistic view towards kids. Manipulation is learned behavior and says much more about the parent than the child.
But honestly, it’s besides the point. This point is that it’s wrong to force kids to eat food barring medical situations.
