For the first time, Jo works with a family with a newborn when she encounters the Peterfreund family in Arizona. Parents Keith and Sonya are so overwhelmed with their three older boys, Jett, 5 Gage, 3 and Trey, 2, that they're missing baby Myles' cues about wet diapers, feedings, etc. Mom literally has to run through the house after the active older boys with Myles hanging off her arm, head bobbing dangerously. Keith is a flight attendant and travels frequently, and Mom doesn't have enough arms for all the work! Neither parent is consistent about discipline, and their go-to punishment is "saucing" the three older kids, putting a dab of hot sauce on their lips. Can Jo show these overwhelmed parents of four how to parent effectively - without condiments?
