Biological and prenatal influences Development begins long before a child reaches school age. Gestational age, fetal growth, birth weight, and perinatal complications can all influence neurodevelopmental trajectory. In the scientific literature, these early biological conditions are associated with later differences…

Development is uneven by design Child development is not a single clock. It is a coordinated but uneven set of biological and behavioral changes across several domains: gross and fine motor skills, receptive and expressive language, cognition, social communication, emotional…

What normal variation means Development is a biological and relational process, not a race. Genes, brain maturation, temperament, health, family routines, cultural practices, nutrition, sleep, and opportunities for movement and communication all shape when children show new skills. Because these…
