My son Christian is VERY picky - and I worry that he doesn't get enough, or that he isn't getting the proper things .... but he *does* eat everything - including veggies - at daycare, and I think it has a lot to do with being around the other toddlers.
Another thing we've noticed is that sometimes if he refuses his food, if we give it to him from our plates - he'll eat it ... I know this isn't a good habit to encourage, but it's only seldom ... for the most part he'll either eat something or he won't.
