Jo helps the Harmony family with their 3 boys: 11-year-old Jake, 5-year-old Ian, and 3-year-old Grant. While Jake is well-behaved, his little brothers aren't. Ian tends to backtalk a lot and fights & torments Grant. Grant has a terrible temper which gets so out of control, he'll bite furniture until he bleeds from his mouth. Also, Grant has terrible separation anxiety and is also known to follow his mom, Erin's car all the way to the highway when she leaves the house. Bedtime is no better when Grant insists on sleeping in his mom's bed, leaving his dad, Jacob to sleep on the living room couch. Can Jo help this family out?
