How long have you tried feeding him?
My son was also unwilling to feed from the spoon initially. It took us about a month for him to get used to the idea. We just kept trying and trying each day until he got the hang of it. We started off with just only 1 teaspoon of cereal mixed with milk then gradually increased the amt.
Your child will eventually get the "idea" of eating from a spoon.
Do not use the bottle to feed cereal. It poses a choking hazard
