Welcome

. He's a very handsome looking bird!!
Falling asleep is normal for his age, he's a baby, so no worries
As for the biting, if it starts to get harder or if he does it to tell you off and stop you from petting him then you'll need to step in wih some training. I find a "naughty cage" and "quiet time" sorts them out petty quickly, parrots are such social birds. You should train him anyway, not just to get rid of the biting habit, it will give his smart little mind some stimulation
