Hmm, it's funny because lately I've been sure she's drained the breast - it feels super soft and DD will take herself off with a drunk milk face or doze off - but if I pinch the breast I do get a strong squirt of milk still, so I'll hand express to see how much is still there and I'll get a few more squirts or a squirt and a steady dribble but then nothing much. So I guess it is at least almost empty?
