I think it's probably common that an employed mother's supply will decrease with time. I'd check with her about stress, adequate pumping time and location, and sleep. I'd also ask about night nursing. In my own case, my supply decreased dramatically the one month I tried pumping instead of nursing my son each time during the day. We solved this by increased night nursing (I even fed him when he was asleep) and eventually rearranging my schedule so I could nurse him at both breaks and lunchtime with pumping reserved for emergencies. -- Anne Montgomery, M.D. [log in to unmask]
