Hi, dont worry too much about the biting, when Buddy was that age i despaired at times because it felt like you couldnt put your hands down to him without him trying to get them in his mouth and chew, infact everything that went near his mouth went in it! Just be really consistent and say 'no bite' everytime he does it and move away from him. It does sink in to them eventually.. honest! Buddy is nearly 5 months now and the only time he tries to chew fingers is when i'm brushing his back legs, he hates that. He's just a baby and its natural it'll pass soon!
