We did the same thing. We told my inlaws that before she was born and my mother-in-law still posted my daughter's birth announcement before my wife was done with skin to skin. She would not stop taking pictures in the post-partum room.
Aw that sucks! We had a similar thing. Told everyone during the pregnancy that we didn't want it on facebook, and MIL still posted information on Facebook.
We deliberately didn't tell anyone when my wife went into labour, as she didn't want anyone else there.
