9lbs 12 oz is a HOSS!!!! My oldest was 8lbs at birth. He turns 19 on the 1st of May. One of the poor nurses there at his birth wasn't very bright. The scale was digital and at one point flashed "7lbs 16oz". In all seriousness, she exclaimed, "another ounce and he would've weighed 8lbs!"

He weighs in at 175 now after dropping 15 pounds since football season. Our daughter tipped the scales at 9lbs 7 ounces. She might tip the scales at 120-125 now at age 17.
