Toddlers are not yet able to verbally express how they feel. Disruptions in their well-being manifest as excessive crying, feeding and growth issues, or sleep problems. The author scientifically describes the emotional world of toddlers and provides a better understanding of psychological conflicts and their treatment options in infancy and early childhood. This equips you with the necessary knowledge to competently advise parents. The volume refers to children up to the age of 3 years. The integrative approach of early prevention and early intervention takes into account traditional psychoanalytic and modern developmental psychological theories.
