Thought I’d respond to this question since I found this post by doing a general search on Yahoo- for other people wondering the same thing… I wanted to make sure I was right about what LN stood for. I agree with Dana67. It means Lactating Nurse. That’s why she was shocked because that meant she breastfed for other mother’s who couldn’t. (Or in LN’s case, she’d breastfeed any child that would “latch on”.) Such a great movie!
