During this stage, an infant's primary source of interaction with the world occurs through the mouth. This includes activities such as sucking, biting, and oral exploration, which play a critical role in the child's development and gratification.

In the oral stage, the pleasure derived from oral activities is fundamental for the infant's sense of comfort and trust.
