My children refuse to eat vegetables.
When they were babies, they ate peas, carrots, beans, squash and sweet potato. My youngest son even liked asparagus. Yet now, they refuse to eat vegetables of any kind other than corn. They will eat fruit but not vegetables.
One of their teammate's dads suggested caesar salad as a good place to start. I'll give it a try. I am hopeful their palates expand as they grow older.
