Some mamas and papas are sticklers for using the anatomically correct names — penis, vagina, breasts, etc. — for private parts. Other parents prefer nicknames — pee pee, tee tee or chi chis, etc. — when talking about the human body. Though she knows the "dictionary terms," I often refer to my daughter's rear in fun loving ways — as tush or bum bum. What terminology does your family use?
