Supernanny (2005)

Season 7: Episode 12

A tough New Jersey cop and his wife find they're in over their heads when dealing with four-year-old triplets and their older brother, Timmy, who's 11. The little ones pester their big brother, destroy things, and run out of the house unsupervised. Dad says, "We have three animals!" The parents think that time-outs don't work, so Mom's method of discipline is to lock the kids in their bedrooms while they scream, and Dad's method is to surrender. Mom is at home full time with the children while dad works, and when he comes home, he's on duty while she heads off to her own job. The relationship between Timmy and his father has deteriorated since the triplets arrived.
