Kitten will not stop biting and scratching

[Raiee2010]

hello ,
i have a 16 week old kitten who will not stop biting and scratching,.. we have had him since he has been 6 weeks old.. and he has been doing it since.. he will not stop no matter what we do i always try distracting him , but it dosent seem to work , and i dont like hiting him like some poeple tell me to do .. BUT... the odd thing is when its just me and him he is fine and his daddy lol ( my boyfriend) gets home he acts out with the biting and scrtaching , he jumps on your arm and wraps his paws around it... im not sure what to do to make him stop , but any help would be great my arms look crazy from him..
