Hi and welcome to BW!
All i can say is that whatever ya do,, stop this now, as ssleighter said, it won't be funny or playful once they get grown, i had the same problem with my pup bama, 'cept that he got me, and bit my lip. Let me tell ya it hurt, but i told him no, set him on the floor and walked away for a gooooood long time i didn't play with him or look at him hardly. he learned that he couldn't do that anymore. And trust me, when they do get grown, they'll do a lot more damage than just a nip on the lip. if he does it with anyone else, let them tell him no as well, and whoever is there,, noone play with him. Just my opinion and agreeing with ssleighter

But on a lighter note, congrats on your new pup, i'm sure you'll have a great time with him
