This must stretch the use of the word natural.I was reading this article about a 'man' who has just had a baby girl.
She/He was a woman that had a sex change to become a man.
She/He married to a woman. I assume a real one this time.
She/He was inseminated artificially.
And it was classed as a natural birth. That stretches the English language somewhat.
Poor little tyke.
