I'm not to sure about the bleeding on the nipple, but when my daughter started going through puberty it began with very sore breasts and very swollen nipples. I took her to our family doctor because they were huge(her nipples) and I was worried. Three weeks later she began her period. Are her nipples dry and cracking? Try using the cream for breast feeding mothers. Sounds funny, but it just may work. Hope I helped a little. Good luck.
