D.P.
I followed the same schedule as some of the others suggested. When I started back to work, I tried to keep at the same frequency he would be eating, which for me was 3 times while I was at work, then nursed at home. This kept my supply regular. As he got bigger and feedings were more spaced out, I cut back to 2 times a day and my supply adjusted. I can tell you, I loved pumping at work. It made me take time out of my busy day to relax and feel I adjusted better because of it.
