Hi Ivy:
The thing with finger foods is that depending on what you are willing to tolerate in the way of messiness you have a full cupboard of finger food. DS will eat almost everything we eat (not spicy though or cheese), from mashed potatoes to rice on his own. the only thing he still eats from a spoon from me is his baby cereal in the morning. SIL's 1 year old dd though won't even eat that from a spoon.
Try .... toast, dry cereals, cheese cubes (small), rice, peas, corn .... anything you can imagine. Cut them up small at first as you might have a crammer like I do (he crams so much into his mouth if he can that he gags sometimes) and let him go to it.
