Being kind and doing something nice for someone else is a great boost for anyone's mental health. Set the children a task of doing one kind, compassionate thing every day and recording it on a sheet. Encourage them to be creative and think up different acts of kindness. It could be holding the door open for someone, looking after a pet, asking if a friend is okay, or doing some volunteer work.
In our Lyfta storyworld, Compassion is Key we meet Leah who shows compassion to her family and her wider community. In the story, we see how this helps her to feel better about herself. Leah misses her recently deceased grandparents but says "When I'm sad, I need to make others happy." So Leah pays regular visits to the nursing home where her grandparents lived and plays her violin to the elderly residents there.
Taking care of animals might be another way children can show compassion and it can also have a very positive effect on mental health. In Dogs Best Friend we meet Erkan from Turkey who lives alone and has few friends but has found his calling and a joy for life in feeding stray animals. "They eat and I feel happy," he says. He believes that by being with the dogs he can "learn to understand the values of life".
