I have a 6 year old who wants to play with other kids but the boys in the area are mean to him.  I need to know how to deal with this without screaming like a mad person.  he got punched for sticking up for his 3 year old sister.  What should I do. I tell him to stay away from those kids and their houses but he just wants to play.  he doesn't care if kids are mean to him.
