Which of the following factors affects a child's development?

A child's development is significantly influenced by their age and temperament. The age of a child is critical because it corresponds to various developmental milestones that children are expected to reach at different stages. For example, infants go through rapid physical and cognitive growth, while toddlers develop language skills and social interactions. Understanding these stages helps caregivers provide appropriate support and activities that meet the child's developmental needs.

Temperament also plays a vital role because it shapes how a child responds to the world around them. Children with different temperamental traits, such as being more easily frustrated or more adaptable, will experience and interact with their environment in unique ways. This can influence their social interactions, learning styles, and even emotional regulation. By considering both age and temperament, caregivers can tailor their approach to support each child's individual growth effectively.
