A father recently told me his relationship with his twelve-year-old son was fragile and becoming fragmented. “What’s wrong with my son?” he asked me. Then came the list: the attitude, the grunting, the closed bedroom door. “He doesn’t even want to join us for meals anymore”, he explained. I hear a version of this question constantly. What’s wrong with my toddler? My eight-year-old? My teenager? We worry about our relationships a lot – and for good reason. Relationships are at the heart of our wellbeing.
