I'm sure I noticed a boost in my milk when I was taking things like fenugreek and blessed thistle, and eating the lactation cookies. Perhaps it was all psychological, but at the time I felt it was helping

I sympathise with you pain with a bitten breast, lol. One of my girls managed to puncture my areola recently and it was right where their teeth would rub when they were latched. It was excruciating. It was almost al painful as breastfeeding when I was pregnant. We ended up doing breastfeeding-gymnastics so that they were in odd positions and their teeth didn't grate on the wound. It still took more than 2 weeks to heal because it kept opening each time they fed. I hope you heal up faster than me!
