Mothers posing nude

So I have a friend who is a Suicide Girl and has been for a long time. For those who don't know what this is, its a nude modelling website for women who don't "fit the mold" of the average model. Ie: tattoos, piercings etc. She has been doing it for a while and is proud of it. Whenever we are gathered in a group she never hesitates to pull out her albums and show them around, and I'm talking full nudity and vag shots. Also she posts them all over fb/ig for the world to see. It drives her husband nuts but she does it anyway. Now she has a 18mo daughter and as soon as the belly was gone she was posing again. I know it is her choice but Personally I think it's disgusting and shows a lack of self respect. It was bad enough when she was childless let alone now that she is supposed to be a role model for a little girl, but that's just my opinion. I'm wondering what you all think. Is this acceptable behaviour?
