Marrying a tall man is all fun and games until you find out he was born at 14 lbs!

Im 16w pregnant with a boy and just found out my husband was born the size if a darn toddler! He was born on time and was 14lbs 26" according to his mama...can this be real?? She doesnt have any pictures....and should i be concerned and tell my OB about his size?
