I keep reading people correcting anyone who says "we are pregnant" saying that he cannot be pregnant therefore it's incorrect... but then saying that "we are having a baby" is correct... when it's not. He's not having a baby either!
Surely the only correct statement then (that I can think of right now anyway) is "We are going to be parents"?
What do you end up saying? I know it's technically incorrect but I still say the "we're going to have a baby" because people seem to not realise that one is incorrect...
