DS1 only has water or milk most of the time and he's nearly 3! As a treat he will ask for "lemon" which is water with some frsh lemon juice squeezed in. He has had straight juice or even soft drink when we're out, but really is just as happy with his version of "juice".

Oh - and he loves cinos - just frothed milk, sometimes with a marshmellow in it as a treat!
