What was the woman talking about?

When Andi and I took Sophie to the Health Department last week for her shots, the "nice" nurse was walking toward us and asking, "So, is this Sophia?".....and just as she was saying Sophia, she turned and looked down at Sophie and loudly exclaimed, "OH Double Chin." Except that she said it all together as if Sophie was Irish...

Sophia O'Doublechin -- it has a certain ring to it. Andi said her chin might be getting a bit out of control, but what's a girl to do?
