A big part of what we do with children is teach them safe and appropriate ways to cope and express themselves. This can help provide concrete examples during times when it is difficult to "find" a coping skill.
"A Mind Jar is a meditation tool to use whenever a child feels stressed, overwhelmed or upset. Imagine the glitter as your thoughts. When you shake the jar, imagine your head full of whirling thoughts, then watch them slowly settle while you calm down".
