When my son was 1yo: I was sitting at the dining table having a cold soda and he walked up to me. He said, "I want *****, daddy". I was shocked because I'd never used language like that in front of him and couldn't imagine where he'd heard it. I said, "Son, what did you say"? He pointed to the soda I had in my and and repeated his request. Well, If I'd had any Pepsi in my mouth I would have sprayed it all over the floor. See, he mispronounced "Pepsi" and used a very naughty word that rhymes with woosie. All I could think at the moment was, that's my boy!!
