Hello everyone! My son is two years old and for the last two months he has been very picky eater. He throws up everything I offer him, and now eats very selectively. I try to offer new food, but he screams and runs away! It's summer fruit and berries season, so I don't give him anything new, only bananas, apples and pears, and even then just a tiny bit...I don't know what to do anymore. I try not to force him, thinking that he will be hungry and eat, but in the end he eats only 2-3 tablespoons. In September he starts kindergarten, maybe seeing other children eating will make him want to eat too.
