In Lincoln, for the first time in her career, Kathryn Mewes comes face-to-face with parents she feels lack the fundamental skills for the role. Ian and Janine Clemmit have tried to give their two boys everything they think they need. They've lavished them with toys and showered them with affection. But there's one thing they have never given them: boundaries. The result is a mum who's lost all control, a dad who is completely overwhelmed and a traumatised family cat. Three-year-old Liam and one-year-old Luke are completely out of control. They hit and bite each other, their parents and the family cat. Kathryn encourages the parents to get back to basics with their parenting, only to make a discovery that could be the key to the family's problems.
