Hi Belle - I don't have a definitive answer for you, but I would think that the reasons why the father was born prematurely and the mother almost was would be important as to whether there is a risk. So based on that I would ask your OB. I have never heard of prematurity being hereditary, but I am not in the medical profession. I do believe that some causes of prematurity such as pre-eclampsia may have an increased risk if someone in your close family has had it before.

Sorry! Probably haven't been much help, but I am sure your OB would be able to advise.
