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 physical, emotional, social, and intellectual development, and involves different parenting styles. There are four main types of parent-child relationships - secure, avoidant, ambivalent, and disorganized. Factors like family structure, social support, relationship history, and culture influence the relationship. A healthy relationship is flexible, connected, has appropriate boundaries, open communication, and discipline. Improving the relationship involves playing games, casual conversation, visiting new places, and rewarding the child.
