Just musings.
I have brought up two kids. When they were very young they'd ask questions.
You know the kind of thing:
"Mummy, why I am I a boy?
Because you have a willy, darling.
Ah, like daddy and [big brother]?
Yes."
"Mummy, what's that in the toilet?
Just some blood. Don't worry, it's normal for women to have that sometimes.
Ah, ok."
It's the most fundamental, obvious stuff. The youngest of kids see it. The very notion that you could say anything else to your kids. It's just mind-boggling.
That is all.
