Neither of my girls know that a rooster is called a rooster. He is called a Cockalittledoo. He also doesn't say, "Cockadoodledoo." He says, "Cockalittledoo." It's so cute that I don't have the heart to tell them the right way to say it. Unfortunately, the other day when I was talking to another adult I couldn't remember the right way to say it either. Cockalittledo has become real language in our house.
