I had the following conversation with my 21-month old son this morning:
Y: Momma?
Me: Momma's on the toilet.
Y: Poo?
Me: No, probably just peeing.
Y: Pee.
Me: Yes, Mama's peeing.
Y: Dingdong?
Me: No, dingdong. Momma's a girl. No dingdong.
Y: Nothing?
Me: Yes, nothing.
Y: Daddy dingdong?
Me: Yes, Daddy has a dingdong.
Y: Papa?
Me: Yes, Grandpa has a dingdong, too.
Y: Yu dingdong.
Me: Yes, Yu has a dingdong. Daddy, Grandpa, Takumi, Takumi's Daddy, and Yu. We all have dingdongs. We're boys. Boys have dingdongs.
Y: Momma?
Me: Momma's a girl. Girls have boobies.
Y: Boobies.
