I think I need some advice on the pumping. My LO is 4 1/2 months old now and I returned to work when she was 13 weeks. I breastfed her until I returned to work with the exception of the once a week bottle to get her used to a bottle (which she still doesn't like). I also pumped because I seemed to have extra. Now that I've returned to work, it seems like I'm not getting as much with each pumping session as I used to. I work 4 days a week and have a strict no pumping/only breastfeeding rule when I'm home. When I first returned to work, I was getting 7 or 8 oz in each session. Now it seems like I'm only getting 2 or 3 sometimes 4 oz in each session. I try hard to get 3 sessions in a day, but some days I'm only able to get 2 in. I have a Medala Pump In Style which was used previously by a close friend. It's a few years old now. I'm wondering if the pump is going bad which will cause me to have supply issues? Do I even have supply issues? How much should I be getting in each pumping session?
