Development in Infants
Newborns often exhibit smiles within the first three days of their lives, especially while sleeping. However these early smiles are spontaneous and are not a response to outside stimulation. These early smiles are referred to as "reflex smiles." Between 6 and 8 weeks, most babies begin to exhibit "social smiles", meaning the baby will smile at his/her caregivers or in response to stimuli. Most babies laugh between 3 and 4 months.

Famous quotes containing the words development and/or infants:
“The work of adult life is not easy. As in childhood, each step presents not only new tasks of development but requires a letting go of the techniques that worked before. With each passage some magic must be given up, some cherished illusion of safety and comfortably familiar sense of self must be cast off, to allow for the greater expansion of our distinctiveness.”
—Gail Sheehy (20th century)
“But O, young beauty of the woods,
Whom Nature courts with fruits and flowers,
Gather the flowers, but spare the buds;
Lest Flora, angry at thy crime
To kill her infants in their prime,
Do quickly make the example yours;
And ere we see,
Nip in the blossom all our hopes and thee.”
—Andrew Marvell (1621–1678)
