i get a wee measuring pot and measure myself 300ml of semi skimmed milk. Does my cereal and a couple or three cups of tea. Think its 4pp if I recall.
You could get away with a splash of milk, but only once in a day. Anything over that you have to point. 2 cups of tea/coffee with semi usually makes 1pp worth of milk. About 3 for 1pp with fully skimmed.
I count sweetner tabs as free, think the powder might gather up points if you use a lot of it. x
