I am so tired and so busy at work these days that I am not able to pump at regular intervals. So I seem to be in-advertantly weaning. My supply has dropped. My LO seems to be OK with it. I can't possibly add a pumping session. I am too tired at night and there is so much to do. I think we did pretty good so far; 18 months, working full time with a commute, not too bad. We still nurse often in the evening and at night, but my breasts seem to ache a whole lot these days. And it seems to take less and less milk to cause the ache. Is this typical of the weaning process?
