More birds and bees

Today we went to a cook out at my friend's home. She is an ObGyn and the boys were curious about what she does. I told them she delivers babies. Max said: you mean like storks do when they drop them into houses? Andrew said: no Max, she delivers them right to their moms - right mom? Uh, ok, sure. But how does she do that? he asks. Very carefully, I said. No really, mom, how does she do it? Well, I said, you know when you feel like you have to go to the bathroom, so you sit on the potty, push real hard? Well, it's like that, but when moms push real hard, out pops a baby. There's laughter in the back seat of the car and then I hear: no really, mom, tell us how it really happens!
