Why is Everyone so Obsessed with Our Post-Baby Bodies?

First it was Shape of a Mother back in April, now it looks like a post from CT Working Moms about post baby bodies is about to go viral. I get that seeing celebrities bounce back in a month is annoying and disheartening, but why are people obsessed with women's post baby bodies?

Part of me thinks it's great that other women are courageous enough to put themselves out there so other moms know they are not alone. But part of me finds it annoying because I know some people just want to gawk.

What do you think? Do you find these real moms sharing their post-baby bodies helpful or is it overkill now?
