As I was giving Devin a bath he grabbed his little male part and said, "This is my goober."
After laughing I informed him that actually it was his penis.
"Oh, my penis," he responded. After a few minutes he declared, "No, it's my goober!"
Last night he came to me complaining that his goober hurt. I thought he needed a diaper change. No, it was clean but he was still complaining, "My goober hurts! Fix my goober!"
I held his pants open so he could adjust himself. It took about 8 minutes and several failed attempts until his goober was in its place!
