When our children were expected and born, we had told everyone we didn't want to know in advance or have any announcement in the delivery room, but find out for ourselves. Our firstborn twins turned out to be a pigeon pair, so that was a doubly lovely experience.
But this is 2020, so the upset mother can simply ignore what the scan and the evidence of her eyes when baby is born and just assign her child to her preferred gender, surely? After all, "Babies aren't born with a sex," as that Labour politician, what's her name, said during the leadership contest recently.
Tongue in cheek, obviously, before anyone thinks I'm recommending child abuse!
