My SIL is very into social media and it's become a big source of tension for me. First my father's shared the news of our engagement on FB before we were able to our family and friends. Then my SIL shared my pregnancy and the gender on her FB page before we could finish telling people. I'm so frightened she will be the first to share my baby's picture before we can. I don't how many times and different ways to get the message across that we are private people. We don't have FB accounts and rarely share our own pictures on IG. I think it's really self centered of people to make our news their own.
