Nothing of any relevance to the mostly male audience here, but, sure, I'll bite.
I was breastfeeding my newborn and one breast was hurting like a bitch. A nurse checked me, which involved looking at my breast, announced I didn't have an infection and shrugged and walked off.
I was in my twenties and had a lot of baggage from being molested as a child. I felt humiliated showing her my tits and then got zero help.
But Heinlein had written something about blocked milk ducts and opening them with a needle. The book description sounds pretty dreadful, but that's not what I did. I sterilized a needle and used it to gently brush dead skin from my nipple, clearing away the blockage from the milk duct.
Problem solved. In like five minutes.
My sister also had some breastfeeding challenges. I don't think I was actually helpful in terms of telling her how to fix it, but I told her my story and encouraged her to keep looking for a solution because the medical establishment not knowing fuck all about supporting breastfeeding moms isn't evidence that it can't be solved. She did find solutions and successfully breastfed instead of throwing in the towel and bottle feeding.
The US completely sucks at supporting breastfeeding. It's awful.
