The development status of children varies widely among countries
Early childhood development is multidimensional, encompassing several aspects of a child’s well-being: physical, social, emotional and mental. Healthy development generally takes place in a series of predictable and common stages: As they grow older and their brain matures, children learn increasingly complex skills and become progressively more independent. However, children can develop at different paces and may reach developmental milestones at different times. What is considered normal child development also varies across cultures and environments, since expectations and parenting strategies may differ not only among countries but also among cultural, ethnic or religious groups within the same country.
