One of my friends decided to take his advice with her daughter, who went through a couple years of eating mostly cheese, pasta, meats and chicken.
She's in her twenties now and is a vegetarian.

They turn pale. Open their eyes wide. Feel faint. I offer them a seat, and repeat, “Forget about vegetables.”
As they gasp for breath, I continue, “When a young child struggles with you over food, you won’t win. The more you struggle, the more he’ll hate whatever you’re trying to shovel into him. Back off. Apologize. Let him know that you know that only he can swallow the stuff you prepare for him.”
As they begin to recover, they stammer, “Really? No vegetables? No green vegetables? No yellow vegetables?”
“Really,” I say. “You can cover them with a multivitamin during this temporary period — usually between 2 and 3 years old – when any battle over food will backfire into even worse nutrition. They’ll make it through this with enough milk, meat, eggs, grains and fruit.” (See our book “Feeding Your Child: The Brazelton Way,” published in 2005 by Da Capo Press, for specific nutritional requirements and strategies for feeding picky eaters. Specific nutritional requirements vary with a child’s age, size and activity.)
