Well Tim, to start with I don't think I'd post my son's name or his weight status on a public message board. Does he know you've done this? My son would have been very upset with me in this circumstance.
I would make your questions a little more generic, not include his name, and start reading lots of past posts here. There's tons of info for every age, you just have to weed through it all. Welcome, there's a lot to be learned here. JMO
