Hey Happy, I really think the pumping might not be doing you any favours right now. I'm sure Amanda and Shiv can offer better advice but I'm pretty convinced that my commitment to pumping for LO1 was part of my problem with mastitis (didn't do it for LO2 and, hey, not mastitis). I'm not saying that no one should ever pump, at all. It's a really useful tool in the mothering toolkit. Just maybe to lay off for now, til things stabilise a bit. Like I say, our resident experts will probably have a better idea, just a feeling of mine.
Hugs.
