Jake went through a stage at round the same age refusing to be fed coz he was independent. I got one of those net food holders for him from the supermarket and he thought it was quite cool and ate stuff out of it he normally wouldn't. As he was teething too I'd freeze bananas and grapes and pop them in it and he knawed away willingly - I think it gave him some relief.
I also gave him bits and pieces off my plate (normally a big no-no in our house but I was desperate coz of the broken sleep we got too!!) and he liked that.
The other thing you might want to do is call Plunketline?
Hugs hun its rough but its just a stage
