I have been back at work part time (Tuesday through Thursday) for about 20 hours a week for the last month (baby is now 11 weeks old). I breastfeed when I'm with baby and pump when I'm at work, usually 2-3 times. By Saturday, my supply is up especially on the right side to the point that it sprays out when nursing. However, it usually decreases by Monday. This week, it was so low that I pumped very little out of the right side on Tuesday and had a noticeable breast size difference. Today (Wednesday), I'm noticing it start to increase again. Baby is still satisfied after nursing, so I know there is still plenty of milk. Any advice for keeping my supply more regular throughout the week even with pumping?
