Mel,

With the food throwing thing....like Ambah has suggested, Olivia was a horror for this if simply left in the high-chair, not eating at the same time or same food as us.....it was as if the throwing food thing was her only way of telling us she was more than ready to go to sitting at the table with us.

It was painful to start with, but after only a few days the food throwing stopped totally and she ate SO much better. I had her propped on 2 old pillows on a dining chair, and simply sat and ate every meal with her........tedious, but effective.......and it also meant that she got the hang of self feeding really quickly too.......

Not sure if that is any help at all?
