HELP! -long post 2 questions-

So my husband and I are fairly private people and are careful about the information about ourselves we put online and we will be especially careful when it comes to sharing things about our future little one on line ( Iv had some close people in my life turn out to me pedophiles needless to say it freaked me out and I became VERY protective about the things I share now) my MIL is VERY open with what she puts online and there's been issues in the past with her and my SIL about her posting things about their child online that she was not ok with so theres problem number one how to I get it through my mother inlaws head that we will have rules and she HAS to follow them?? I want to be polite and not make her fee like she can't post ANYTHING, I just want her to only post things I have posted on my public page. Is that to much to ask? Now problem number 2, I am not close to my MIL but she thinks we are SUPER close, like I love her and she's great we just aren't close. So when I'm in labor I ONLY want my husband my mother and the doctors in the delivery room. Any suggestions on how to gently let her know this? I'm more than happy to have her come in after the baby is born and hold and love them I just don't want her in the room for the actual birth. To me it's a private intimate thing I mean I'm bringing life into this world so I think I should be able to say who can and can't be in the room when I do so. I just don't want to alienate her. I know she will be upset but this is one of those situations where I believe my wants trump what others want.
