Babies ensure that the human species survives, and many believe that the joy and peace that the smile of an infant brings represents true happiness here on earth. Babies are small, helpless, and innocent. It is impossible to see their smile or hear a coo and not have your heart melt. For new parents babies are a source of intense pride, incredible wonderment, and a new and terrible set of fears. Knowing that you are responsible for this little creature can be a heart stopping realization, but the joy that these bundles provide far outweighs the sleepless nights and endless worry.
