I have a hollow-legged 8.5 yo ds, who is driving me MAD with near-constant declarations of starvation.
My problem is the ridiculously limited range of foods he will eat. He doesn't like cheese, eggs, tuna (any fish), humous (or any pulses), even potatoes I have to force down him 
This thread reminded me of porridge, which he likes a lot for a certain length of time, but then tends to 'go off it' again.
Other than that, he just ends up snacking on cereal (less sugary ones like shreddies), endless bread (at least it's home-made mostly wholemeal) or fruit (apples, bananas, oranges or kiwis, which he quickly gets bored of and says they don't fill him up anyway).
I also always turn to bread for a snack, and I know that we should both be eating protein rather than carbs to fill us up - but he doesn't like most of the cheap-ish quick protein types, and I have neither the time nor the budget to be making endless bacon sarnies (tho he'd love them!)
Any ideas..?
