My son is boycotting baby food?

I'm not sure of a solution, but I will say that when my son had teeth coming in he didn't want to do anything but nurse either. Although, usually there was a fall back food, like bananas and sweet potatoes. He looooved both of those pureed foods and when he would go back to only wanting to nurse, those foods are what he would tolorate. I would say that it's probably due to teething, it's not forever. Just keep offering him food, if he eats it, great! If not, then just keep trying. He'll eat it when he's ready.
