My conversation with Sam in the car this morning.
Sam: Ooh Mummy, there's a lady on a horse over there.
Me: So there is, we'll have to drive slowly past them, so we don't frighten the horse.
Sam: OK Mummy. Errr, Mummy, where do horses come from?
Oh no - THAT conversation.
Me: They come from their Mummy horses tummy Sam.
Sam: Oh. I KNOW THAT!! But how do they get in there?
Me: Well, they just grow. Like you grew in my tummy.
Sam: So where did the Mummy horse come from?
Me: Errrr, from their Mummy too.
Sam: Oh Mummy, you just don't know where they come from do you? I'll tell you. Horses come from the factory and cows come from the cow shop.
