In addition to the above, when he flattens and opens his mouth, pop a little piece of fruit in his mouth. This works so well, and is amazingly cute. They get this confused look on their face, and they get their greens too!.
It's all about patience and perservirance. Don't be afraid of him, when they are that young, it doesn't really hurt all that much to be bitten. What you will most definately want to do is find a room in the house that is small and completely closed off where he cant gent into any trouble wandering or licking things. You might have to actually create this area yourself, but you'll have to make sure there is NO way he can escape.
Then, sit or lie on the ground. Make yourself comfortable, and let him run around you. Just observe him, make sure he doesn't get into any trouble, and maybe have some tastey waxworms or a piece of fruit handy if he comes by to check you out. When you're down at his level, not coming at him from above, and, essencially being a piece of furnature, he'll learn to recognize you're not a threat to him and in fact, supply the tastey treats.
Another thing you can do, is about an hour after lights out when he's calm and cooling off gently take him out of his enclosue and put him on your lap or your chest while you watch tv or whatever. Then you're not only furnature and provider of tastey treats, but you're warm and comfortable too!
