The Child is an almost universal symbol for the soul's transformation. The child is whole, not yet divided. When we would heal the mind, we ask this child to speak to us.
When silence, wonder, adoration are diminished, so are human beings. We imagine we can get by on love and indeed we can. But love shrivels up and dies in the absence of contemplation and adoration. Love, human love, needs to be transfigured, transcended, if it is to be true to its deepest self.
