He tries to be firm, but Dylan just yells at him, (his father has alot to do with this he told the kids years ago, that they don't have to listen to him) but DH has been around since Dylan was 4 years old.
Plus DH sets stupid punishments & never sticks to it,which is something he has been told to fix, cos it proves nothing that way. The kids get grounded "til christmas" then let off in a week.It doesn't give him a good hold over them, cos he changes it all the time, I have tried to tell him, maybe this time he will.
