Mindfulness is focusing on the present moment while calmly acknowledging and accepting one's thoughts, feelings, and body sensations as they are. The use of mindfulness practices on children and adolescents is burgeoning. This chapter covers the meaning and elements of mindfulness, their measurement, the various techniques, and exercises exclusive for children. Such techniques are typically individualized, tailor-made, personalized, contextualized, play-based, activity-oriented, reward-oriented, and maintained at the child's developmental level. Mindfulness parenting is vital. A mindful parent is aware of one's thoughts and feelings; is responsive to the child's needs, thoughts, and feelings; is better at regulating own emotions; is less critical of oneself or the child; is better at standing back from situations and avoiding an impulsive reaction. Issues related to professionalism, formal institutions for training mindfulness, and ongoing research on this theme, their achievements, and setbacks are listed before providing future directions for work in this area.
