By junk food I mean chips and cookies and candy lol. I wouldn't be too worried except that he is starting to loose weight. If I don't let him have any of his junk food and we are eating things that he doesn't like, he just won't eat. I have tried chopping veggies up into tiny pieces and sneaking them into hamburgers and things like that, but he will literally pull the whole thing apart and take out what he doesn't like. He has been doing this for 2 years now with no change except for whether or not he likes bananas from one week to the next, but his ped. is still telling me it's a phase. I love his pediatrician, he is great with my daughter and always listens to what I have to say, but for whatever reason, he just isn't listening with my son. But, he has a lot of patients with ADHD, so maybe he is just more comfortable with that.
