Help! 10 pound baby!!! Advice, stories, or what you've heard.

Anyone have a 10 pound baby!!!? My hubby was born at over 10 pounds, I was born at 6.7. I'm only 5'1" and at 98 lbs. I've always been tiny and I don't have big hips. I heard that my baby is most likely going to be the size my baby daddy was. Myth or is there some truth there???! The person that told me is an RN and has been studying midwifery. So now I'm petrified.
