My 13 mo will barely feed himself at all. There are a handful of things that he won't immediately throw on the ground. Even if he's hungry, and will eat when I feed him with a spoon or by hand, most of the time he will throw it immediately off the high chair tray. Even if I put just one or two pieces on the tray at a time. He used to be a bit better but I feel at fault because I think I was a bit guarded to avoid messes. The ironic part... I started with baby led weaning!
