A Maryland dad was skeptical of parent training. He worried it would feel like being graded as a parent. His BCBA started slow, working through one routine at a time. The bedtime routine first. Then mealtimes.
Six months in, this dad was running his son's reinforcement system during weekend visits to his in-laws and felt for the first time like he understood why his son did what he did. He still does parent training sessions every other week.
