Yes this may be the case. I was born at 28 weeks and struggled a lot with learning and sport, although I am now 6ft 1inches and a solid build. So it's hard to say if physically reached my full growth as well. My doctor recently said that I would have been a bigger person if I was full term. Anyway, to parents who have very prem babies. Pay extra care to the learning and make sure they understand that, as they get older, they're not dumb and can excell in other areas. I now have my own business, travelled the world, worked in sales and was the top sales person. My difficulty in learning forced me to work harder than the average person.
