Having found these pictures, I decided I never want my daughter to be hungry at the end of a feed, not even a little tiny bit. So we started making all her top up bottles 100mls to be on the safe side. Then at the 4am feed she seemed to have done pretty well on the boob, so I wondered about taking some milk out before we gave her the bottle. And then decided that wasn't fair to her, I should just heat up the bottle as it was. So I did. And all she wanted was 40mls. 60mls of breastmilk down the sink. That's one whole pumping session. That really hurts.
