Hi My name is M. And I have the same problem with my son he's 7 and is over weight because he is also an asthmatic, What I try to do is keep him busy and limit the amount of junk food and sweets. I try to give him fruits and natural juices,and i try to get him into some sports making sure he doesn't over exort himself.It's a good idea getting him into swimming.Hope my advice is usefull and Good Luck.
