Yoga practice for preschool children should be in short, 15-minute sessions. Explain some of the philosophies behind yoga in terms the children can easily understand. Encourage children to listen to their breathing, feel their muscles stretching, and begin to listen to their bodies while letting their minds be still. Yoga instructors will often create modified versions of the poses, or relate the poses to animals or nature, which the children can easily relate to. Instructors might also create an animated story where the children must act out certain parts with yoga poses.
