I was trying to figure out where you're from Kate. In the UK we have milkshakes with extra protein in, most supermarkets carry them. 15g to 25g of protein and they really nice, should tide her over until lunch. I get the Aldi ones and the Pro Milk brand as well. If you're not in the UK there might be an equivalent locally. Sometimes it's much easier to down a cold milkshake than eat a meal.
