Hi, My 3 year old son has food preference and doesn't eat vegetables or fruits. He eats nuts, apples, rice at times ,non-veg( chicken,mutton fish), and drinks milk. I have tried to feed him vegetables and fruits but shows tantrums and he stopped eating eggs and bananas as well. But he is active and plays around. As he needs to go to school this year and need to change his food preference. please guide me .
