I don't react, generally just eat mine and then potter around the kitchen tidying up until she tells me she's "finished". She gets fishfingers max once a week, and sausages max every other week, plus eggy bread once or twice a week (for the protein /iron more than anything). The only cheese she will eat is dairylea on oatcakes (I let her have dairylea once or twice a week), no to hummous. The rest of the time, she survives on vegetables and potatoes.
It's such a minefield - don't want to turn mealtimes into a battle, don't want her to end up anaemic from too little iron, trying to manage the sugar / salt content so it's not too high!
Thanks for the link re: higher protein fruit and veg - that's good to know.
I will keep my fingers crossed it's just a phase, me and dh eat a wide varied diet, and offer her things off our plates.
