Dear Connor,
We had this conversation during your shower yesterday:
You (as you were cleaning your private parts): What's inside my penis balls?
Me: [stifled laughter] Penis balls? Those are actually called your testicles.
You: Oh. What's inside my testicles?
Me: Nothing. <--- what I should have said
Me: Well, when you get older, they'll have stuff to make a baby. <---what I actually said, opening up the trap door
You: There's a baby inside my penis balls?!
Me: No, no. You need a boy and a girl to make a baby. You need the stuff from your penis ba--I mean, your testicles and an egg from a girl. When girls are older, they have eggs inside their bodies.
You: Do the eggs hatch?
Me: No, they're not like birds. You need to put the stuff in your testicles together with an egg to make a baby and then the baby grows in the girl's tummy.
You (asking the obvious next question): How do put the stuff in your testicles and the egg together?
Me (realizing this is as far as I want to take the birds and bees conversation this time): You can ask Daddy when he gets home.
You: Ok.
Oye. Luckily for Daddy, you forgot all about this when you saw him!
Love,
Mom
