When my two youngest GC were tiny fussy eaters I tried a trick that seemed to work; I cooked a variety of vegetables, and put a few spoons of each into some very small ramekin type dishes, put the dishes onto their dinner plates with the main item, and asked them to try each thing and tell me what they thought. Remarkably they did - I solemnly wrote down their findings on a notepad, and they seemed to like the novelty of carrots in one dish, peas in another, and for a good while after this they clamoured for a 'special' dinner so that they could be food critics! They eat well now, and are still quite young, so I do hope you have a happy time with the GC, and try not to worry - it's just not worth it as so many posts on here have demonstrated. x
