And that's how babies are made!

Our granddaughter entertained the assembled family yesterday with her explanation of life, which she figured out after much pondering.  I am not making this up. It all starts when a girl kisses a boy.  The boy's spit has fertilizer and it gets into a  small hole in her tongue.  When she swallows  the egg goes into her stomach where it grows for two months. Then the baby comes out of her privacies. Oh.  The reason girls can't show their na-nays, but boys can, is because the girl's na-nays contain milk and she can't let it get stolen.  Boys don't have milk in their na-nays, so they don't have to hide them.
