B.G.
Are you offering just finger foods or are you trying to spoon feed him? Both of my boys had no interest in me feeding them. They were (and still are) both very big on "I do it myself!"
If you think he's at all inclined to want to do it for himself, rather than be fed by you, just go with foods that he can actually pick up and eat himself.
My boys had pasta, eggs, cheese, grapes, green beans. When they were about 11 or 12 months we started just eating together. Whatever I was eating, they would eat. We would sit at the table together. I would make an extra big plate for myself and put a little bit of everything on their tray. If there was something they ate, I would replace it. Once they started getting antsy or throwing food, I took that to mean they were full and let them get down and play.
Just keep experimenting. He'll find what he likes.
