Why not put kindness into the front frame of your setting! Every week the children could have a 'Kindness Meeting'. At this meeting children could make positive statements about children in their setting. Children and teachers could also be encouraged to share what they have witnessed during the week that they consider are 'random acts of kindness'.
In this way you would be making visible and putting into action that you value kindness in your community. In this way everyone is encouraged to focus on the positive and establish a culture of kindness in your place.
If you have a 'kindness story' to share, please email me at email@example.com with the story and an image so we can share the joy on our Kindness Blog.
