I posted about this on Facebook, but I figured I'd bring it here for wider discussion.
One of my favorite bloggers, The Skeptical OB, posted about a female professor who got in trouble because she breastfed her baby while giving the lecture.
Apparently, her baby was sick, so she couldn't bring her to class. She instead brought the baby to the lecture she was teaching. Instead of asking her teaching assistant to look after the baby, she instead let the baby roam around the lecture hall. At one point, she had to stop the lecture because the baby was eating a paper clip. Another time she had to stop because the baby was getting close to an electrical outlet. And then she decided to breastfeed while giving the lecture.
I agree with Skeptical OB that there's pretty much nothing appropriate about what she did. As a professor, I think you owe your students more respect than to simultaneously babysit while you're teaching a class.
And while I think breastfeeding is wonderful and would never want to discourage it, I think I'd be pretty distracted by a professor breastfeeding while trying to teach me.
