Re: finger food
If you are avoiding wheat, you don't want to give him cheerios. If you can find a wheat free alternative though he's almost certainly ready to try something like that. My little man liked rice or corn chex (which is wheat and gluten free). Rice or quinoa pasta is a good treat and usually a favorite.
You can also give him any kinds of fruit or veggie. Things with built in handles are great, like broccoli florets, sweet potato "fries" cooked in the oven, apple "fries", pear slices (these are good cause they are really soft and mushable), steamed carrot sticks, etc.
