we had a very similar problem with DD.although hers was that she didn't want to be spoon fed anymore and was a bit hit and miss with finger foods. i think this possibly another independence thing (and Sasha is very independent!).
What we did with Sasha in the end was put the food in front of her and show her how to eat it with her fingers.i'm not talking about traditional finger foods either like fruit etc i mean messy foods like pasta, spaghetti, cous cous and so on.
