I Am NOT Monica

So this past week Christian has started to call me Monica. I am NOT Monica...I am mommy. It is really cute the way he says it. He draws it out and adds his own special way of saying it. He giggles when I freak out after he says Monica. He used to say, "Thank you, Mommy" when I would give him something or do something for him; now it is "Thank you, Monica". GRRRR!!!
