This assignment delves into the multifaceted world of child development, focusing on the social and cognitive aspects of children between 2-5 years old. It utilizes Piaget's Cognitive Development Theory and Erikson's Social Development Theory to analyze a case study of a 3-year-old named Jack who faces challenges in developing toileting skills and establishing autonomy due to his mother's lack of motivation and his absence from a trusted guardian figure. The paper highlights the crucial role nurses play in fostering child development by understanding these theories and tailoring care plans to individual needs.
