Alright, so I've been looking up the average size of a newborn head....35cm. Boston's was 40.6cm. And although that was the most painful thing I've ever done and hopefully ever will do, I LOVE his big ole head...especially with his scrawny arms now. But I am praying for a 36cm or smaller head on this next kid. So that means his head was 16"...does that mean I dialated to a 16 instead of a 10? haha!
