My six year old son is having issues going to his dads house and I don't know what to do for him. He says his dad get really mad and screams and screams at him. He also said his dad pushed and old man who asked for money. Recently his dad left so many harassing voice mails on the little leaque managers phone that we were kicked off the team. What can I do? Should I go back to mediation? I can't talk to the dad.
