"Mum, how do babies get out?"
We didn't actually have a car crash as I wondered how to answer my older son's query, but that was mainly because it was early and most Russians are far too sensible to be on the road before 10 o'clock on a Saturday morning.
I decided to bite the bullet. "Well, ladies have a special hole between their legs, and the baby comes out through there. Mostly."
Silence whilst this was digested. Then, in a very sceptical tone of voice; "Reeeeeaaaaallly?"
"Yes, really."
"How big is the hole?"
"Well, normally it's very small. It has to stretch - a lot - for the baby to get out."
There was a sharp intake of breath. "That must hurt very much."
I laughed ruefully, wondering if I might actually be managing to educate a male in how amazing women are, that they can bear the pain of childbirth. "It most certainly does."
Then; "Wow. Those poor babies."
"Yeah" piped up Boy #2. "Those poor babies..."
Dear Lord. Give me strength.
