"Developmentally" refers to the process of growth and change that occurs over the course of a person's life, from infancy through adulthood. This can refer to physical, cognitive, emotional, and social changes that occur during different stages of life. Developmental psychology is the study of these changes and how they impact individuals and their behavior. Developmental milestones are important markers of progress that are typically achieved at specific ages or stages of development, and are used to track a child's growth and development. Understanding developmental stages is important in fields such as education, healthcare, and child development. Our primary focus is education.
