I've been following the debate around ED's fertility privilege article with interest. I have every sympathy for her with regards to her struggles to conceive, and i understand how painful it is to live in a culture that glorifies, indeed almost deifies motherhood when one is having issues with fertility. However - as many posters have already pointed out - if she wants to talk about the concept of being mindful when posting about motherhood and children, she has to recognise and accept that she must be mindful when posting her own successes and blessings, as they may cause similar pain.
I have long been aware that sharing certain aspects of my life may cause pain to others. I have therefore made the choice not to post anything about my life at all. The potential pain it may cause isn't worth it for me. But if I did decide to share certain things about my own life, I would understand that I had no right to judge what others post about theirs. Even as someone who doesn't post about my own life, I still don't have the right to judge what others post about theirs. We are not entitled to judge others against our own arbitrary moral standards (especially if our standards are contradictory/hypocritical). We can only live by our own values. When we do, it becomes easier to abstain from passing judgement on what others choose to do.
