What do I do? He bit my friend's little boy today and drew blood. I put him in the corner for 2 minutes, talked it through with him and took him over to say sorry. And he just laughed. I could have died of shame. We left straight away. My friend was ok about it. He learnt nothing, as he bit his sister just before bed.
He's been doing it for about 4 months. He bit one friend's little boy and drew blood through a vest, top and cardi! The friend although seemingly ok at the time has ignored my emails since
.
Am I destined to stay at home and never mix with other children for the next 2 or 3 years? 
Will I have a big bully of a boy forever? I just don't know what to do.
