My ds is 9 mo and also shows very little interest in food. I started solids with him at 6 months - he happily ate whatever I gave him (rice, fruits and veggies) for a month and then right about 7 months he stopped letting me spoon feed him. None of the "tricks" such as "give him one spoon and feed him with the other" worked. It was extremely frustrating, to say the least.
So, I moved on to finger foods soon after the strike began. I came across the baby-led-weaning idea here on mumsnet and thought that was the answer - I had visions of my db adorably shoving fistfuls of food in his mouth and eating "entire roast dinners" as other mothers swear their babies do. Not surprisingly it wasn't a magic bullet. Lots of the food I gave him went straight on the floor, most was just ignored and he'd lick a piece here and there. If he swallowed the equivalent of a few spoonfuls a meal it was a victory.
He's 9 months now and I've seen a very gradual increase in the amount of food he actually swallows and in his general interest level. But he still doesn't eat anything near what other babies his age likely do.
In case it helps, these are the foods I've had the most success with, relatively speaking: ripe avocado sliced in long strips; bananas sliced in long strips; toast soldiers slathered in butter or cream cheese; the cow & gate rusks - both savory and sweet, with cream cheese; strips of mango; very ripe pears, plums, peaches or nectarines - I cut in half, peel off some skin, hold it up to db's mouth and he sucks on it and scrapes some into his mouth; rice cakes with fruit puree or somethin spread on top; Ella's kitchen puree pouches which he sometimes lets me squirt right in his mouth. Again, he only eats a very tiny bit of any of these, but at least he tries.
Also, fwiw, my db has steadily dropped to the 2%. He sees a paed who is not very concerned with his weight. She says that weight is just one thing to look at and if you look at the whole child it is clear that my db is doing ok (he is also very happy and loony-like). My best friend is a paed and she has also reassured me that he seems to be doing just fine.
Oh, and in reference to Tapster's comment, my db was mostly FF'd.
So, hope that some of this helps. I've posted before trying to find other people dealing with the same issue and no one ever responded. It's very frustrating to deal with and I find the suggestions given by friends who have babies that eat well very annoying, although I know that they mean well.
Anyway, good luck and try not to worry too much.
