We need to work on this

So quite a few months ago I tried to explain to Lauren the fact that girls are born with all their "baby-making" eggs already in place.  She firmly grasped the idea, even if she didn't grasp the correct knowledge.  She told me earlier today that she had a tummy ache.  I was thinking it may have been the plateful of salami and cheese she'd eaten earlier, but she had other ideas.  "Mama, my tummy is upset because the tiny babies inside there are kicking me."
