Am I the one being disrespectful?

Last night I told my mom that I didn't want enyone posting anything to social media when the baby comes. I told her to at least give it a day or so. I don't want pictures of him online when he looks like an alien. And she got butt hurt! I also told her, if people (family only) come to my house I would just like them to call my husband or myself before showing up. She told me I was being rude to her and my mother in law. Am I the one who is in the wrong?
