Just looking for advice. I am throwing my daughter's first birthday party. My sister-in-law is pregnant and wanted to reveal the gender of her baby at my daughter's birthday party. I told my brother that the day was supposed to be about my daughter and I wished that they would find another time to announce. Instead of calling me, they just posted the gender on Facebook. My guess is that I made them both mad. Was I right in telling them this? How do I handle them posting it on Facebook without calling?
