At that age I don't think your daughter could have had a word for something she could not see. As she grows up, at any given age she might understand the difference, yet not want to learn any details. In fact, I know a woman in her forties who once told me she had no desire to know anything more anatomical than a single word for everything "down there." This revelation surprised both me and my wife, who is an ob/gyn physician. But the woman I'm referring to did not grow up in an "Our bodies, Ourselves" kind of household -- which I guess also shows why that book really is needed.
