I've been watching a baby's growth and development for 4.5 months now and
have been highly entertained. This "developmental trail" is relentless even
though the baby can't possibly know what the purpose of grasping his other
hand could be or how success leads to the next step. It is obvious that the
baby delights in accomplishing each task. Maybe babies get that
"biochemical cascade that rewards the brain," too.
