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.
