Oh I'm not doing it for what I'm getting out of the pump (which is zero to 5 mil...so nothing), but just for the extra stimulation. There is a part of me that is worried about the amount coming out, seeing as I was EE for a few weeks when DD was young and couldn't attach, and I was a 1.5L a day girl...but no, I only started pumping a few nights ago and then once before that on NYE...the time I started to notice all the other signs, but mostly DD's terrible output
