I remember with DS we filled the water up to the ml then added the powder. However I now realise that nearly everything refers to oz so we are following these instead. I now notice though that 60ml is not equal to 2 oz and so on all the way up the bottle, so if we were doing 240ml, this is more than 8 oz, which means the powder to water ratio isn't the same with the ml and oz. According to the side of the formula tub, it is 1 sccop or powder to 1 oz or 1 scoop to 30ml but this doens't make sense.
What do you follow?
