Why is my two and a half year old boy such a picky eater?

Question

He used to eat any veggie, meat, or fruit then he turned two and all he wants is cheese and bread. I keep offering veggies and meat and fruit on his plate every night regardless of if he will eat it or not but he doesn't even touch it.

Answer 1

Starve him, he'll eat anything,then he'll find out that food aint so bad

Answer 2

because he is growing more now and needs more fat for tissue development and more energy from carbs ( bread is an excellent source)....plus his digestive tract is more advanced and can handle the new stuff better
