Another cause can be excessive stimulation or even nipple piercing! My 19 year old daughter had her nipples pierced and cleans them frequently. A couple of months after the piercing, she began to lactate and expressed a couple of ounces to show me. We've gone through all the screening tests so it's not any medical issue just a side effect sometimes seen with the new fad of nipple piercing. I did a google and actually came up with some other cases of this happening post piercing. I've discussed not stimulating the breasts so much and to watch for mastitis but at least my daughter ow knows when she's ready and has a baby- her system works really well :) Lisa JOnes RN IBCLC RLC *********************************************** To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or digest) To unsubscribe: unsubscribe lactnet All commands go to [log in to unmask] The LACTNET mailing list is powered by L-Soft's renowned LISTSERV(R) list management software together with L-Soft's LSMTP(R) mailer for lightning fast mail delivery.
