my son was the same way. As an infant he wouldn't eat baby food. the dr said no problem, but he was constipated all of the time. as a young kid, he still wouldn't eat vegs, other than corn (Dr. said corn doesn't count it's a starch), He was a skinny little kid, Then puberty came, he still wouldn't eat vegs, but he gained alot of weight, because of the starch in pasta (about all he would eat) He's 18 now and 5'9" 210 lbs, he actually will eat a few vegs now, he says his taste changed. when he was young, he ate alot of pasta and peanut butter, his endochrinologist said buy TONS of fruit and let him eat as much as he would like! He is doing better now, but it worried me and his DR.. The Dr. use to try to tell him to try a salad every now and then, but he never has.Try things with real fruit like frozen fruit bars, jello with real fruit. Apple or bannana chips. Apple cinnamon rice cakes. good luck.
