Wait a minute. Take a deep breath. Listen to yourself. You say he knows sit and stand. Then you say he won't learn. Hello?!?! I'm thinking that is pretty remarkable for a 12wk old baby. Keyword baby.
He wants to play. He doesn't know biting hurts. Maybe you could try immediately biting him back so he knows why you are saying no. I think his littermates and mother would have bitten him and he would have learned the limits.
Anyway, to get him to do what you have done so far at such a young age is pretty remarkable and shows he is very trainable and you are going to be a great trainer. Just remember to have fun and let yourself, your family and especially him enjoy each other a bit more.
