Chapters in Treating Preschool Children range from developmental and behavioral principles guiding work with children from birth through five years of age to specific problems, including autistic-spectrum disorders, gender issues, attachment disorders, feeding disorders, elimination disorders, child abuse, and common sleep disturbances. We assume that the editors chose to focus on categories described within the DSM-IV nosology of childhood psychiatric disorders, but in doing so they have omitted many of the problems most commonly seen in this age group—namely, behavioral aggression, extreme emotional outbursts, social withdrawal or shyness, high activity level, oppositionality, and defiance.
