How old is yours now?? Our 6'3.5" son was always a success story, they don't know why he was born early, he just was. No glasses, no learning disabilities.
He had a couple of hard years, to begin with, but he's great now.
My brother was born at 25 weeks back in 1970, his first five years were tough, but then he just took off. He was a nationally ranked runner in high school and later went on to complete Ranger school.
A very precocious 7 years old, 4'3 and growing fast. A success story as well.
