A side note: all of this started a few weeks ago after a plugged duct on the right cleared, and around the same time I ran into a doorway with my left breast, hitting it pretty hard. No bruising or outward signs of injury, but is that the cause of the low production on that side? Or does it just seem low because I have such high flow in the right? Probably doesn’t matter, but how to fix these issues?!?

AND, all of this in the setting of planning to go back to work in a month, and needing to start building a storage of milk. What/when to pump?

Wow, I was wondering if anyone on here would comment on babies that were older than a few weeks. I am experiencing the one side preference with my 5 month old as well. She prefers the right side. For about the first 3 months I could get about 6 to 7 ounces out of both. But now it’s only about 3 1/2 too 4 ounces out of the “good” side and maybe MAYBE an ounce out of the “other” side (double pumping with Medela). My concern is what happens when her appetite increases as she gets older? I know they say your body will adjust but it is still a MIND concern for me. I don’t know if there’s anyone who was able to do something to “fix” the uneven milk flow late in the game (5 months).

I’ve written quite a bit about breastfeeding after breast cancer. Take a look in the side bar under “cancer” if you haven’t already. I’ve also got two posts up on how to perform a breast self-exam on lactating breasts and a video on how to perform a BSE. Good for you for being proactive and finding that lump.

Best wishes for your health.

However, after baby turned 1, I found a lump in the non-producing breast, and it turns out I had stage 0 breast cancer, and the pathology report clearly stated that my milk ducts were almost completely filled with cancer cells. That explained uneven milk production. I encourage anyone who has a serious imbalance in milk production to seek medical help. You won’t find anything written about this on the Internet–anyway I didn’t.
