After decades of teaching preschool-age children, I am always happy to be reminded that infants are not only for changing, feeding, and rocking, but they are for playing with, too. Recently, my new granddaughter has filled the role of playmate for me, and she is teaching me new ways to play. Although babies cannot run, jump, or ride a trike, they can imitate, anticipate, imagine, experiment, smile, wiggle, bounce, spit, make gurgling sounds, and more. We grown-ups go to great extremes to elicit even a fleeting smile from an infant. This leads to mutual giggling, chuckling, and even outright laughing - the beginning of play.
