Social Smile

Social Smile

There are very early smiles with some infants.  They may smile in their sleep or if they passed gas or pooped and now they feel better.  But a social smile is when infants smile because they see a certain person’s face who makes them happy.  Beginning at 6 to 9 weeks old infants will smile at certain people they like (Berger, 2018; Feldman, 2014).
