Re: Does your period affect Milk Supply?
hi mama! yes, your period can lower your supply, but i think the MAIN thing that you're seeing right now is the normal supply adjustment that happens right around this age of your baby. almost everyone starts with some oversupply (to make sure the newborn gets fed) and then sometime around 3 months things regulate so your body doesn't have to keep overproducing. 2-3 oz per session is a much more normal amount to pump than 7-8.
you are exclusively pumping, right? i think that if you want to increase your supply again you're going to have to pump more. every 3-4 hours is just not enough. you'll want to aim for 8-10 pump sessions per 24 hours, and yes, the night pumping is important. you might be able to get away without it if you get in enough pumping during the day, but that will also be tough.
i'm sorry to bring bad news, mama!
ps - why are you exclusively pumping? do you want to work on getting baby back to the breast, which is generally a much easier way of providing milk and keeping up supply? we're pretty good at helping with that too.
