Expression of Happiness and Smile Types
The purpose of this paper is to describe infant expression of happiness and to inform findings of research relating to smile types in infants as well as to inform about potential relationships between smile types, play type and parent gender.

Despite this useful information, facial expression is the form of communication that provides the most reliable cues (Berk, 2002).

Happiness in an emotion that brings baby and caregiver closer to each other, it brings them together and helps develop a warm and supportive relationship (Berk, 2002). Soon after birth babies show reflexive smiling which may be seen to express fullness after eating or may be a smile during sleep, this is because reflexive smiles usually occur when the infant is not in
