What do you give her for dinner? A close friend of mine still gives her 6 year old salad or fruit salad most nights of the week. He won't eat dinner type meals & it's not unhealthy, so better than nothing.

If she's having meals for lunch, I'd try lighter foods for dinner. Fruit & yoghurt or similar.

I'm not into making a fuss at dinner time though. Not one of my kids like to eat the same things on their dinner plate each night, but as long as what they do eat isn't junk, then I'm not overly worried about it. I don't give DS potatoes, because he's never, since he was a baby, eaten potato - unless it's oven fried. He's mostly meat, fish, fruit & some salady stuff. DD2 is more meat & pasta's, so I try keep to whole meal pasta's & bread etc. DD1 is a fruit, salad, vegie kid. But not fussed on mixed meals (stir fry/spag bol), DD3 pretty much eats it all lol. She's awesome when it comes to dinner time!
