I don't do bottles. By the time kids start coming to me (11/12 months) they should be able to use a sippy cup. I do milk at lunch and that's it. I have a fellow daycare provider friend who had a dcg like this. So much milk all the time the girl developed a liver issue. At this age, kids should be getting a lot of calcium and nutrients from food. Now if a child asked me for a second cup of milk or whatever, I would oblige but I don't allow it to become a crutch for the child
