I was putting away dishes when I heard little kid behind me saying, "Mumum, look at my naked butt. Look at it," in an angry voice.
"No. What are you talking about? You need to knock it off with the naked butt stuff," I said, trying to ignore him.
"My baby butt is gone. It's gone! Look! It's gone!" he said sadly.
I glanced down to see his shorts pulled down and his naked butt out, looking like his naked butt normally does. "What are you talking about, silly?"
"It's a good boy butt. I got a good boy butt. Not a baby butt."
(He says good boy instead of big boy, despite us correcting him a thousand times.)
"Oh stop. Your butt's fine. It's still little."
"It's not a baby butt."
"It's a 3-year-old's butt, not really a big boy butt yet. You're still a baby. You'll always be my baby."
"I not 3, mumum, I 2."
"You'll be 3 in 3 days."
"I still 2! Don't call me 3! I not a good boy, I a baby."
"Okay, baby," I agreed, in order to end this argument.
His constant refusal to grow up has me a little worried, as I could see this lasting well into his 30s.
