My boy's are doing so much better than other's with Duchenne's, because we pushed them with alot of drive and will but most of all love.Dont ever give up. You are his strength. I will alway's be here for you. I need to pay it forward because I have been so blessed. Do get him on prednesone as soon as possible, it keep's them mobile longer, my boy's didnt get into thier chair's untill they were 12. May God Bless You All.
