The term wasn't coined at Northern at all - she isn't the only one with an opposite. But yes, Sway opposite is a better term for sure, I'll use that in the future, but if people with opposites find it too painful then of course I won't be posting stats anymore =)
I've also been on the other side of where Northern is - I lost my daughter and had two sons, my second son we very much would've liked to have been a girl and I was upset when I found out it was a boy, especially as my partner didn't want any more children after our second son was born, so I get how she feels completely.
Northern - have you considered doing PGD after this baby? (hope u don't mind me asking).
