Well during one of my maternity leaves I read everything I could about lactation (usually I was holding big textbooks and reading while I was nursing - I guess reading about the science of lactation helped my let down!). This was because I was taught NOTHING about human lactation during either medical school or residency. AnnaM, your elective sounds like a great idea! Now I am far more knowledgeable about lactation than any of my partners, I use this knowledge everyday at work. And of course, personal experience does not hurt either...
