I'm new here, and have a question...my LO is 3 weeks old and I have been BFing exclusively. I decided it was time to start trying to build a supply of EBM for when we go out, and when I return to work (eventually). In the breast feeding class I took the lactation consultant suggested pumping a little bit after each feeding during the day, to get a full bottle by the end of the day. I started doing that on a Wednesday, and got a full bottle by Wednesday night. I skipped pumping on Thursday, and on Friday did the little bit of pumping after each feeding again. However, I noticed on Friday that LO was extremely hungry more often than usual. He had been on a pretty solid 3 hour schedule for almost a 1.5 weeks, but was waking up to feed (and eating voraciously when he did) every 1.5 - 2 hours. I couldn't help wondering if somehow the pumping was depleting my supply. How long will it take my milk supply to catch up with the supplemental pumping? Or could it be my timing? For whatever reason, I can't seem to manage to go straight from BF to the pump, and usually end up doing the supplemental pumping about 30 mins to 1 hour after his feeding. I want to build up a supply, but also want to make sure I'm leaving enough in my breast for him to get what he needs. Does it sound like a supply issue, or is it just coincidence that he started being hungry more around the time I started to pump?
