I wonder if the feeling that you're having that bf needs no documentation is because you've seen all the documentation in the world not diswade people from smoking, drinking, and using formula so there must be an unmet need out there. It's great to tell people about the advantages of bf and to have the latest research to back us up but if I were a childbirth instructor and new that half of my class would just get offended at the mention of benefits (thus the need for the latest research) then I might try to tackle the reasons people choose not too bf. For example after the class helped me come up with a list of some of the benefits of bf I could have the class help me make a list of all the reasons a person might choose not to bf, or a list of the problems a person who bfs might encounter, then go through the list and teach the alternatives/solutions. I think the people who are most passionate against bf are those who already had disapointing bf experiences or those who feel that there is some hurtle before them that would make bf difficult to unbearable. It's good that the childbirth instructor doesn't want to presume that she can tell people what they should do for their babies and in there own individual circumstances, but if she can get ideas flowing on !how! these couples might be able to make bf work for them then she has a great class that even the people who were planning on bfing would get a lot of information out of.
