That is specifically why I have forbidden my mother in law from being told! She can't keep a secret to save her life. If I have my way (which I don't usually), she won't find out until I'm at least 20 weeks... not sure if I can keep it from her that long, but I hope I can get close. It helps that she's out of the country right now, but the second I tell her, the entire family will know. She's better than social media!
