I've been researching fussy eaters latley. My DS isn't overly keen on dinner either, but it's because he is too tired, I think I need to bring tea time back about half an hour. but anywho, it sounds like she's fighting for control.
We have an eat what your given rule too, and if your hungry enough you will eat it.
She might be old enough for you to start geting her to help choose what is for tea before you make it, then she might eat it, because it was her choice already?? after all she is already showing you she wan'ts to choose, but it's after you've done all the hard work
