I know that I'm lucky to work in an organization that is supportive of my pumping schedule. I'm lucky to have a locking door on my office. Saying that, I feel like my colleagues' and my own patience are wearing thin. My little man (4months old) still usually feeds for at least an hour every 2-3 hours when I'm not at work (3 oz expressed milk every 2-3 hours while I'm at work). This also is inconvenient (don't live somewhere where it is socially acceptable to breastfeed in public) but very doable. My problem is the pumping. I have to pump 35 - 50 minutes a session. Often my letdown only occurs at the 20 or 30 minute mark, and that is never more than a drip. In the morning, at work, I usually pump 3.5 - 5 oz and in the afternoon I usually pump 2.5 - 4 oz. I go home to feed my lil one at lunch and pump one more time after he goes to sleep, usually 1.5 - 2.5 oz. A majority of my home time is spent feeding him. I double pump with the Ameda Purely Yours... Using the 25 mm flanges. Have tried all 3 standard size flanges and the 24 mm inserts (my nipples measure about 20 mm but increase in size with feeding or pumping). I'm still waiting on the 21 mm inserts to come in the mail, but am not hopeful. Is there anything else I can do to increase efficiency in pumping? I try to eat well, drink lots of water, drink mothers milk tea, and take more milk plus. Am I supposed to do more than drip? I truly appreciate any advice.
