No biting

me-me

So apparently my son who is 13 months has learnt to bite when he doesn’t like somthing we do. How can I stop this I sternly say no and move him away from me(he only bites me) somtimes he gets he did bad and cry’s other times he thinks it funny... I really don’t no what to do some people say bite him back I’m not a physical punishment kinda mom so that’s a hard no!
