Gotta be quick but Haroula don't stress at all about your drop in production with expressing - it is perfectly normal and your supply IS NOT dropping at all. Boobs (and brains) know when there is a real baby attached to you and you will produce less on the pump until you get used to it. So much so that many women who express at work take their "baby porn" with them - photos of their bub to stimulate milk. I get heaps more when Ollie is in the room than not. Please don't worry about this at ALL!
