I have just ben expressing and for some reason, I really struggled to get 5oz out. I normally do 7 easily, so I don't know what that was all about! Anyway, I decanted it into a freezer milk bag and went to seal it - then knocked the whole thing flying! Most of it went everywhere, I think I managed to keep about 2oz of it!! Why did I have to spill my liquid gold??!!! Especially after discovering Oliver polishes of 13oz for a night feed. My God, I'll never get enough together for a night out at this rate!!! ETA: I've just made myself feel a bit better though, when I remembered Necee lost a whole freezer full of the stuff. It could have been worse!
