Mental Health of Infants

The following sections describe key concepts related to the mental health of infants. These concepts enhance what is included in the previous definition:

 “Developing capacity” highlights the extraordinarily rapid pace of growth and change in the first 3 years. Although newborns experience intense feelings and are active partners in their relationships with adults, the differentiation and complexity of a young child’s emotional and social development increases markedly over time.

 Infants and toddlers initially depend heavily on adults to help them experience, regulate, and express emotions. Infants’ cries and coos evoke strong reactions in their caregivers. An infant’s ability to master feelings develops through give and take.

 Through relationships with parents and other caregivers, infants and toddlers learn what people expect of them and what they can expect of other people. Infants and toddlers learn through what they experience within relationships and what they observe in adult’s interactions with one another.

 Infants and toddlers share and communicate feelings and experiences with significant caregivers and other children. Infants and toddlers interact with one another in emotionally meaningful ways. Parents and caregivers help young children name the feelings and understand their effect on others.

 The drive to explore and master one’s environment is inborn in humans. An essential component of infants’ and toddlers’ well-being is the self-esteem that grows out of mastering their bodies and the environment as well as sharing that mastery with parents and significant caregivers.

 Every child is a unique blend of characteristics; infants’ and toddlers’ developmental pathways will reflect not only their individual constitutional differences but also the contributions of their caregiving environments. Temperament, or the way an individual approaches the world, influences how tentatively or vigorously an infant might engage with a new person, toy, or situation.

 The state of adults’ emotional well-being and life circumstances profoundly affects the quality of infant-caregiver relationships as well as infant and toddler mental health. Parents and other significant caregivers bring their own temperament and past experiences to relationships.

 Culture influences every aspect of human development. This broad influence affects the way that infant mental health is understood; the goals and expectations adults have for young children’s development; and the childrearing practices that parents and caregivers use to promote, protect, or restore infants’ and toddlers’ mental health.
