The Baby with the Big Head

A week and a half ago, on my bi-weekly visit to the doctors office, I had an ultrasound to check the position of the baby. I haven't seen her in several months so it was just amazing to see her little face, staring straight at me with her precious little lips and her eyes blinking. The doctor checked a few things. She is head down, she is still a girl, and upon futher inspection, she has a really big head. A normal size body, but a really big head. WHAT?!?! What does this mean in the world of percentiles? Next time I go in, I'm going to ask him if I have a really big pelvis. You know, just what all girls want.
