my son is 4 and 2 weeks ago we were told that he has duchenne and some of the reason that he might be so agressive is because he lack in running and doing normal stuff will he every settel down and be my sweet boy again? and if he is already this agresive then would it be a good idea to put him on steroids like i have haerd so many people talk about on here and the doctor mentioned puttin him on steriods.
