I think I've seen little bottles of milk at the store. You could buy those and put them in her lunch. Another option might be soy milk, because I have seen some in little juice containers (the ones with the straws, like HI-C and Capri Sun). The soy milk comes if different flavors, but I'm not sure if it's all sugar free. I don't know how much help any of this was, but those were just a couple things that came to mind. ~CindyLynn~
