Supernanny (2005)

Season 4: Episode 6

Brenda and Bill Dostal think that the problem is with their misbehaving son, but Jo quickly realizes he's just acting out due to Mom and Dad's problems. Five-year-old Zachary literally chases Mom around the house trying to claw her when she attempts the timeout technique. Her arms are bloody after his attacks! His little sister Erin, 3, is overshadowed by Zachary's outrageous behavior. Bill blames Brenda for not controlling Zachary, and Brenda doesn't trust Bill to curb his own temper when dealing with the children. As a result, communication between the parents has shut down, and Zachary is so naughty that play dates are fraught with trouble. Brenda fears her marriage may not last if they don't get help.
