I mean, if I cooked something with onions, mushrooms and peppers, would that be three portions or would it be just one because by the time I've dished it up there's not so much there for each person?
And if dd2 has cornflakes with banana, grapes and slices of pear in it, is that three or just one because there's only so much fruit you can fit in a child's cereal bowl (with cornflakes)?
