LO is 9mos old. Over the past 3 weeks my pump output has been dropping off quite a bit.

Until this point, I'd been pretty consistently pumping between 11 and 13 oz per day, and had been sending baby with 12oz (as three 4oz bottles).

It was also typical for my pump output to be higher on Monday/Tuesday after spending the weekend together and to drop off by an ounce or two over the course of the week.

In the past few weeks my daily pumping output has gone down to more like 9-11oz per day, and I tend to have the lowest output early in the work week.

What's going on?
