I've just realised that I have contradicted myself above!
I said I give Charlie milk in a beaker as a drink, but I had heard that you shouldn't give them milk as a drink until they're 1 !!!
What I meant was....... Charlie has his formula milk in a bottle when he wakes, and another bottle before he goes bed. During the day, he'll have a beaker of water to drink. But occassionally I will give him a small drink of cows milk in his beaker, but it's usually as an accompiament to food. Should that be formula too? He seems to like it ice-cold and you can't make the comfort up and store it - it seperates if you cool it.
