Which of the following is NOT a developmental factor mentioned?

Clothing style is not considered a developmental factor in the context of child growth and development. While clothing may influence a child's self-image or social interactions, it does not directly impact their physical, cognitive, emotional, or social development. In contrast, feeding practices and comforting methods play significant roles in a child's nutritional health and emotional security, both of which are crucial for healthy development. Additionally, play space availability directly affects a child's opportunities for play and exploration, which are essential for learning and growth. Thus, among the provided options, clothing style stands out as an unrelated factor to developmental processes.
