A lot of people in another post said they hate picky eaters, and their kids eat what they fix no matter what.
So I have a few questions for you.
You fix spaghetti for dinner. (Or frankly any kind of pasta with a red sauce.) You have cucumber salad, steamed carrots and fresh mixed fruit for dinner (strawberries, blue berries, raspberries, and cut gapes.)
One of your children doesn't like the sauce. Would you just give them plain pasta?
What if your child just liked raw carrots and not steamed? Would you save him some uncooked?
All of these things can be done easily without becoming a "short order cook."
