I think it's more about the grown up's attitude where kids and healthy food are concerned. With younger kids, if you offer them things like apples and carrot sticks in a way that makes it sound like a treat ("Ooh - I could really go for a big bowl of fruit salad right now, do you want some? It's my favourite.") then kids will be interested. Also, I think margaretlayton was right when she said to get kids involved in making food fun. You can get plastic sandwich cutters that make dinosaur shapes in bread, and simple plastic cookie cutters (plastic so that there are no cut fingers) work well too. If you use wholemeal bread with a salad filling, there's a lot of slow release energy there as well as vitamins so it's a really good snack. Also, porridge with a spoonfull of cocoa and one of sugar is not too unhealthy and because of the chocolate flavour will feel like a real treat. The oats give essential fibre, the milk provides calcium and as a wholegrain product, it's just generally good all round!
