The parent-child relationship consists of unique behaviors, feelings, and expectations between a parent and child. Parenting is the process of promoting a child's development from infancy to adulthood using different styles such as authoritarian, authoritative, permissive, or detached. Factors like family structure, social support, relationship history, and culture influence the parent-child relationship. A healthy relationship is maintained through flexible communication, discipline, boundaries, and connecting with the child by playing games, casual conversation, and visiting new places together.
