Emma & Susan, have either of you tried going straight to finger food? By this I mean small chunks of very cooked soft fruits & veggies? At least this way, he spoon doesn't have to be involved. Baby can pick up the pieces of food by him/herself.
You will probably have to help, I have been doing a bit of this with Kirsty . She hasn't mastered the pincer grip (thumb & index finger) yet, she picks things up in her fist then can't eat it because it's inside her hand
I usually put some pieces on the tray on her highchair, and help by putting some in her mouth with my fingers. I've found sweet potato or pear is good to begin with as these are very soft when cooked.
