I would be very surprised if mom had an abundance of milk one day and then "no milk" the next. Depending on what kind of pump this mom is using, it is very likely her supply dropped from exclusively pumping and not breastfeeding. We see NICU moms on a good rental pump make a lot the first few weeks if they pump enough, and then it drops in amount "naturally" by the end of the first month. We are now telling moms to pumping 10 times in 24 hours for the first two weeks to have a really good supply. The old 6-8 times in 24 hours just doesn't seem enough to make a milk supply that lasts over the weeks. (Thanks to Nancy Mohrbacher for this information.) My questions would be how often is mom pumping, is she pumping at least once during the night, is she pumping with big enough flanges, is she pumping long enough time, does her machine work properly, are her valves in good shape? Someone who is not breastfeeding needs to pump at least 8 times in 24 hours for at least 15 minutes, I see they need to keep going until the milk drops absolutely stop and don't come back -- often 20-25 minutes double. Single pumping works best if mom does it 5 minutes per breast, back and forth 3-4 times per breast for a total of 30-40 minutes pumping -- not 15-20 minutes on each side before switching. I have also worked with several mothers who did better on the non-computerized rental pumps. Once they switch to a non-computerized model, they start making more milk a week later. What I find with my WIC moms is that they stop pumping enough and go down to about 4-5 times in 24 hours which drops their supply down drastically. The other thing is that sleeping all night is another milk supply killer. When my clients start doing this, they drop down to less and less milk. This is why I don't understand the myth that pumping and bottle feeding is easier!!! It is so much harder to keep the supply going and to dedicate the time and effort.
