I'm thinking of forcing my picky eater son to eat what I made
Why might you force your picky eater son to eat what you made? Will that work?
I want him to like my food, young men need nutrition
Forcing him to eat anything is going to backfire on you. Try to offer him foods he does not like mixed with foods he does like to get him to eat better.
The child needs to listen to me.
With children, you need to be adaptable with your parenting. A child should listen to their parent, but sometimes you should also listen to your child.
