This isn't a reference book, but a reference I have used many times: American Academy of Pediatrics, Section on Breastfeeding, Summer 2004 newsletter. Catherine Watson Genna is one of the authors. Good description and pictures. http://tinyurl.com/cdon9b June Winfield, Board Chairman Northwest Mothers Milk Bank Portland, Oregon www.nwmmb.org *********************************************** 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.
