IT’S a battle that many parents may be familiar with. In the red corner, a toddler wears a frown, the downturned mouth in defiance as blood rises to colour the cheeks suggesting the threat of a little tantrum. Meanwhile, in the green corner sits a very innocent-looking broccoli floret. Or spinach. Or whatever vegetable or food that happens to disagree with the toddler. The outcome of such a battle can go either way, depending on the parent’s strategy and level of patience.
