In this episode, Jo heads to Maple Grove to help out a single mother whose partner left her to raise their three children on her own. Heather Thompson (32) is so overwhelmed that she can't discipline the children. While oldest child Nicholas (10 1/2) is well-behaved, it's his younger siblings Lucy-Rose (6) and Caleb (4) that cause mayhem in the household. Lucy-Rose kicks, hits and bites her mother and younger brother, while Caleb refuses to eat any fruit and vegetables, preferring to eat pudding for dinner. Can Jo help this family out before disaster strikes?
