Dear Lactnet Friends: The 5% figure is an ESTIMATE, someone's guess. I heard somewhere, long ago, that if a species had more than a 3% failure in any aspect of its reproductive process, that species did not survive. If anyone knows of a source for this, I would be most grateful. warmly, Nikki Lee RN, BSN, Mother of 2, MS, IBCLC, CCE, CIMI, ANLC, CKC Author:* Complementary and Alternative Medicine in Breastfeeding Therapy* www.breastfeedingalwaysbest.com https://www.facebook.com/nikkileehealth *********************************************** Archives: http://community.lsoft.com/archives/LACTNET.html To reach list owners: [log in to unmask] Mail all list management commands to: [log in to unmask] COMMANDS: 1.
