I have been exclusively breastfeeding for 6 months... Did not have a milk supply problem initially. Went back to work at 8 weeks, been pumping 2 times a day in a 13-hr workday (because there just never seems to be enough break time for a third pumping session). Used to bring home 16-18 oz, now I'm bringing home only 9-11 oz. Baby drinks 24 oz. (four 6 oz. bottles) while I am at work, and then I usually nurse her again when I get home. Tried to introduce solids (rice cereal and oatmeal) 2 weeks ago, and she cut down to nursing only 4 times a day instead of 5. Then baby got really constipated and pediatrician recommended stopping the solids and going back to strictly breastfeeding, which I did. Her bowels still are not moving like they should be, which has me worried. And I don't know why my milk supply seems to be going down... is it because of not pumping enough at work? Or maybe because of introducing the solids for a week? I am worried... I'm a first-time mama, and I really want to nurse all the way to 12 months. Thanks in advance for any help or advice.
