I agree with the other Mom...Plus, your son won't starve. He may go to bed hungry a few times, but then he'll learn and start trying things. What I do with my kids, if they just dont' want something because it's new, they have to at least try it. You can tell if they really don't like it or if they're just saying they don't and go from there. I also have them on some great vitamins, so it's not as big a deal if they don't happen to eat everything good for them. They're the best vitamins out there - they get absorbed the most!
Anway, I hope this helps!! Good luck and remember it does get easier as he gets older! (at least the eating part lol)
