You are definitely at the good place for learning Korean. Your son might also learn with kc101 but to be honest, I think he will learn much faster than you will and at some point, the "learning together" won't work any more. But let him explain to you what he knows, that's also a very good strategy. However don't forget to check the "dictionary meaning" of the word he teaches you, I've noticed that the children's definitions of some words are not always exact...
There's also a website made specially for kids, I haven't checked it in a while but you might have a look: www.teenkorean.net
