As it gets closer and closer to my due date I need some help.

I need to figure out how to word that I don't want people to share, or post their own photos of my child without being rude.

SO and I have both agreed that if we don't intervene his family will post pictures of them to people I do not wish to see my child.

We both have those people blocked and we are confident that they will not see the pictures from us on facebook.

If they do wish to post pictures I would be ok if they block those who can see them or don't at all.

Can anyone help me word this and give me more reasoning on why this should be the parents decision? I know his family will through a hissy fit.

Also, the reason my SO and I would post pictures is because we will be able to know exactly who sees it.
