Development from birth to 19 years involves several domains and is comprised of both a sequence and rate, with the former being the order of milestones and the latter being the individual pace of progression through these milestones.
Understanding Development from Birth to 19 Years
Development in children and young people from birth to 19 years comprises physical development, language and communication, intellectual/cognitive development, social, emotional and behavioural development, and moral development. These are often broken down into stages based on age, such as prenatal, infant, child, adolescent, and adult stages, each with distinct developmental milestones and normative events.
Sequence vs. Rate of Development
The sequence of development refers to the predictable order in which children typically achieve developmental milestones, such as sitting, crawling, and walking. In contrast, the rate of development refers to the pace at which a child progresses through the sequence and is influenced by biological and environmental factors. While developmental milestones occur in a similar sequence for most children, the rate can vary significantly from child to child.
