My Son Is Almost 6 Years Of Age We Have

my son is almost 6 years of age we have been seeing a orthopedic team for more than 2 years
both his feet in toe he has a really bad left side his left tibia is 5-10mm short, his left knee dislocates more than 30 times a day, his left thema rotates and has slight bow, left hip has popped out twice in last 2 weeks, his surgeons have said they want to leave him they dont want to do surgery or any other medical procedures until he's age 10-12 just wanting more opinions as I don't think that was the best answer we were hoping for I think if left alone it would be more painful and could do more damage what are your thoughts?
