There are so many good things to learn from the simplicity of a children's story. The subject of this story is about how a little girl learns she is loved. Another lesson can be learned from the parents in the story, one on how to patiently teach and guide a child to discover truth on their own so they can more fully own their learning of important things.
"Love Rays" by Paula Sacks is part of the "Attachment Project" series (an excellent resource by the way). Loving bonds between an individual and other human beings are important for healthy development at any stage of life, and the special bonds between parent and child developed at a young age can make a world of difference for how that child grows up and approaches life's many adventures.
