Infantilism (physiological disorder)

In medicine, Infantilism is an obsolete term for various, often unrelated disorders of human development, up to developmental disability, which consist of retention of the physical and/or psychological characteristics of early developmental stages (infant, child) into a relatively advanced age. Similarly to some other medical terms (cretinism, idiotism), "infantilism"/"infantile" may be used pejoratively (synonymous to "immature").
