Mother under heavy criticism for bathing bare with 4 year old son.

A young woman in the United States has been facing heavy backlash and support alike after she posted pics of her completely bare in a bathtub with her 4 year old son. She posted the pictures ( which cannot be posted here) on
her Facebook account and opposing views have not seize since then. A lot of people speak vehemently against it while some don't see anything wrong with that.

On what side are you in? Do you think it's proper of her to do that? Or do you see nothing wrong with it? Put in your views.
