Here are loads of links from Kellymom on pumping and working, I hope all works out ok, there are lots of things you can try, as I said before eating aots really helped me, drinking loads and pumping often, whenever I read a book, watched TV etc to get supply up. Some people also use fenugreek but i didn't try that. I understand the pressure, Leorah was MSPI and wouldn't drink allergy free formula though by about 11 months she was eating more solids and started to drink some fortified rice milk.
