Our Lab puppy is 9 weeks old and is very nippy. We always tell him off when he does nip. Is there anything else that we can do or will he just grow out of it?!
Id' stop telling him off - like kids, puppies find that negative attention is better than no attention at all - if they get ignored when they nip (you move away from them and don't even acknowledge their existence for a few minutes, don't even look at them or talk about them because they know then that they have your attention) they will stop. When they come to you and want to play 'nicely' then reward them with lots of fuss and attention :)
