My 3.5year old is small-30 lbs& has been picky w/ food, not eating 3 meals, only wants snacks or junk. what can i do to stop her f/ losing weight?

Picky eater: Are there other picky eaters in the household? Children learn patterns from those around them: if older children or parents won't eat a particular food, little ones probably won't, either. Do not give in to letting the child eat snack food. Set good examples by eating healthful foods—fruits, veggies, lean protein; your child will earn to like them, too. Otherwise, see pediatrician for evaluation.
