The children are well aware I have another name besides Mommy. As a matter of fact, R calls me by my first and last name frequently. Interestingly, it is NOT just when he is demanding something, he actually uses it as a term of endearment. "JXXX Scott, you are my JXXX Scott."
A couple of days ago we were trying to explain that Daddy has a grown up name too, since when I call him by anything other than "Daddy" a very confused look often comes across the faces of the children.
M: Do you kow what Daddy's grown up name is?
M: Some people call him that, but he has another name he was called as a little boy. Think. What does Mommy call Daddy?
