C&G Follow on Milk cartons

[FizzyBoobly]

The carton states 200ml. When emptied into a bottle it goes up to the 220ml mark. Am I having an off day/being a bit thick or what??

What bottles are you using? I found that some of them aren't exactly accurate with the measurements.

Dr Browns bottles and that's before the 'blue tube bit' goes in if that makes sense. I'm sure when we were using the stage 1 milk it went up to 200ml on the same bottles. Baffled!
