TMI photo? (Breastfeeding)

People are obnoxious sometimes. I posted this photo of my daughter of Facebook. I don’t post a lot of breastfeeding photos. Not because I am ashamed or anything, I just don’t. I thought my daughter was super cute in this one, so I posted it with a bunch of other photos of her from the week. My step mom (who couldn’t be less like me), comments, “nice boob shot.” Like, really? Is it rude if I delete the comment? I think it’s obnoxious and inappropriate and I don’t want to be associated with it, frankly.
