Many people like to keep their pregnancies under wraps, but they may choose to divulge the information to a select few family and friends on the basis that they'll keep it a secret too.
But one woman was left furious after her mother-in-law revealed her pregnancy on Facebook just minutes after she was told, using the hashtag 'new baby'.
She said that she and her partner told everyone to "please keep it off socials", as they didn't want to post anything on there, but the mother-in-law went against her wishes, and she took to Reddit's 'Just no MIL' forum to rage.
