Having taught (mostly) kindergarten in the same school for 29 years, I've had the privilege to see many children grow into adults. This continuity of experience has been of great benefit. It's taught me to see, value, and listen to the child in me and in everyone I meet whether an infant or a great grandparent.
It's just as Leo Rosten, says:
“You can understand and relate to most people better if you look at them—no matter how old or impressive they may be—as if they are children. For most of us never really grow up or mature all that much—we simply grow taller. O, to be sure, we laugh less and play less and wear uncomfortable disguises like adults, but beneath the costume is the child we always are."
