I can't believe I'm about to tell you this, but my dd takes a Fruitshoot bottle! My dd never drinks anything prepacked (honest!), but one of my mindees arrived with a Fruitshoot and when it was empty I re-filled it for dd. Its just big enough, but small enough iyswim, to fit in her lunch box. I need to get a new one actually, I put it in the dishwasher and it has melted into a funny shape. Still works though!
