Social media rules for baby

I am due on dec 21, and I am very worried about my child's pictures and name being strewn across the internet and not protected. I don't want to be that crazy annoying mom but once something is on Facebook- pretty much anyone can see it. My Inlaws have a horrible tendency to share ALL of my pictures/posts about baby, and I want to have rules for social media when my daughter is born, but I don't want to sound bitchy. Is anyone else experiencing these concerns or have any advice? Just want my daughter to be protected! I don't want her name on Facebook at all. Thinking of having a nickname for her for Facebook and only allowin picture sharing if they ask Permission first.
