The period between twelve and eighteen months places a child on a one-way bridge. Infancy is a thing of the past and toddlerhood is straight ahead. A baby still? Not really, but neither is he a toddler and that is the key to understanding this phase of growth. Take a couple of photos because the child leaving infancy will not resemble the child entering toddlerhood six months down the road. This is a time of metamorphosis when his potential for learning seems limitless, his budding curiosity unquenchable and his energy level never seems to diminish.
