Calm Down! Sit Still! Pay Attention! Phrases told to children constantly, but with limited success. We are asking children to perform these actions without first teaching them how to be calm, still or attentive. Enter the M.D.C, the Mindful Dino Crew. Six dinosaur friends who learn to control their bodies, emotions and reactions through mindfulness. Dactyl Joins the Crew is the first book in the series which explains what mindfulness is and why it is important. Dactyl often finds herself getting in trouble until her friend Brac suggests she use mindfulness to control her reactions. Brac describes how to be mindful and invites Dactyl to join his crew, the M.D.C!
