As I was putting Jeena to bed tonight, she started rubbing my arm.
Me: What are you doing?
Jeena: Saying good night to the baby!!
Me: Where is the baby?
Jeena: The baby is in your arm!
Me: Really? How do you know?
Jeena: Remember the lady took blood from your arm to see how the little baby was doing??
Case closed. The baby lives in my arm.
