0–2 Years: Bodily Sensations, the Mouth, and the Primary Attachment

The Primary Bond and the Development of Emotional Security

During the first two years of life, psychosexual development is grounded in the emotional bond established with primary caregivers.

This primary bond satisfies basic biological needs for nourishment, warmth, and hygiene, while also laying the foundation for emotional security and trust in the environment.

Through physical support, eye contact, and constant attention when the baby cries or is distressed, the infant experiences the pleasurable sensation of feeling safely held.

This emotional support allows the earliest experiences of care to be imprinted on the child’s psyche as satisfying experiences, laying the essential foundation for learning intimate communication and the future development of healthy, balanced interpersonal relationships.

The Oral Zone as a Center of Pleasure and Knowledge

In this early period, the mouth and lips emerge as the primary erogenous zone and the focal point for exploring the world.

Originally linked to the act of breastfeeding or nursing, sucking provides the infant with a constant sense of well-being that transcends simple biological nourishment.

The pleasure derived from sucking becomes a mechanism for soothing internal tension and exploring the physical qualities of objects.

From this early discovery arise autoerotic behaviors, such as thumb-sucking, tongue-sucking, or pacifier use.

These expressions allow the child to autonomously recreate the warm sensation of the primary bond, actively managing their daily moments of profound solitude or rest.

Tactile stimulation and the establishment of bodily boundaries

The baby’s entire skin surface is highly sensitive to external stimuli.

Caresses, hugs, tickles, and skin-to-skin contact trigger pleasant sensations that help the infant become aware of his or her own body structure.

By manipulating their hands, feet, and limbs, and by putting objects in their mouth, infants gradually come to understand where their body begins and ends. Affective sensory stimulation teaches that the body communicates and conveys well-being.

This learning is essential for children to gradually distinguish between various pleasant and unpleasant sensations, promoting a fully integrated and positive perceptual development.

Genital Self-Exploration and the Role of Adults

Between six and eighteen months, the process of bodily discovery naturally leads to the exploration of the genitals.

This contact stems from a developmental curiosity to explore all parts of the body, without any erotic intent or elaborate fantasy.

Physiological responses, such as involuntary erections upon touch or urination, are completely normal and to be expected.

Both the family and the school should address these expressions with naturalness, hygiene, and calm, always using the correct anatomical terms for the corresponding private parts.

Avoiding rejection, guilt, or shame ensures that the child develops a fully healthy experience of their own body during childhood.

Summary

Psychosexual development between the ages of zero and two is consolidated through the primary emotional bond. Continuous attention to biological and emotional needs fosters a sense of security, laying the foundation for intimate communication.

The mouth is the primary area of exploration and sensory pleasure through sucking. This experience helps soothe tension and gives rise to healthy autoerotic behaviors that help the baby cope with feelings of loneliness.

Tactile stimulation and self-exploration of the limbs and genitals help define bodily boundaries. The adult’s role is to support this process with calmness, naturalness, affection, and good hygiene, avoiding guilt or taboos.
