Clearly, it will make them lesbians. Which is why there are so many more now than "back in the old days", because more babies are EBF'd now... oh, wait. No, no they're not. Myth BUSTED!
Also, I'm virtually certain dh was not BF'd past a year, and he's DEFINITELY a boob man... must have come from watching his mom BF his younger sisters, I guess.
No one has personally told me anything dumb about BF'ing yet, but I'm sure it will happen once I actually start doing it.
