By this point I'm laughing so hard I have tears in my eyes. Charlie isn't sure why I'm laughing but he's pretty sure he's the cause and seems quite proud of himself. Finally I ask him to show me what he's talking about. He runs into his room and returns with this toy bull. And he shows me the pink penis where the milk comes from. After I'm done laughing I explain about girl cows and teats.
Thank goodness for anatomically correct toys.
P.S. Charlie also calls teats "teeth." I love that kid!
