Sorry, Katie

So I've been teaching Katie to say "sorry" to others (including, and mostly, the dog) when she hits them. She's been very good about it and has really taken it to heart. How do I know this? Well, when she accidentally bumps into something, she says "Sorry, Katie." Perhaps I should be concerned that she is referring to herself in the third person, but at this stage, I'm just glad she's saying "sorry."
