    Teaching Compassion to Children

    This year, Argonne Child Development Center is sponsoring a Pajama and Book Drive for the children in a local transitional living community. Children and families of the center donate pajamas and books that will be distributed to the children of families that are between homelessness and returning to an independent life.  

    You can find family resources for teaching compassion to your child at the Bright Horizons Growing Givers webpage.
