Hi Shaynee, welcome to the group that no one wishes they had to be a member of. Perhaps to clarify things the docs will ask for a muscle biopsy to see how much dystrophin your son is making. None would mean Duchenne, some would mean Becker's.
Try to get to one of the DMD specialists (you are probably seeing one in Columbus), especially a Certified Duchenne Care Center . They will be up on the latest info, research and standards of care for your boy. But if you can't, you can't.
Give yourselves a break, you don't need to learn everything all at once. Your son is still very young. Simon was not diagnosed until he was 6, but we knew something was up at 3 years and I started mentioning things to the pediatrician, who did send us to the Shriner's hospital, but the orthopedic surgeon said he was fine!
Great people here to ask your questions to.
Best of luck in your journey, we are all at different points on the same road :)
Have heard of several boys being diagnosed in a similar story to yours. Simon met all his milestones, except that he never really crawled, he preferred to roll everywhere, lol. A bit of a speech delay, but was told it was due to his father being French Canadian and me speaking English! And when he did begin to walk right about 12 months of age he was always falling forward and banging his forehead, had an almost permanent little bruise there, poor kid.
