Developmental Milestones
What are developmental milestones?
Developmental milestones are functional skills or age-specific tasks that most children learn or demonstrate in predictable stages of growth.
How do they develop?
Developmental milestones are like stepping stones, with each milestone building upon the previous to support a child’s growth and development. For example, most children learn to crawl and pull themselves up to a standing position before they learn to walk. A child’s development progresses through four major skill areas:
- Movement and muscle
- Communication and expression
- Play and social
- Thinking and problem solving
In reality, each milestone does not develop in isolation, as development in one area is reinforced and enhanced by growth in others.
Every child is unique and develops, learns and plays at their own pace.
This natural progression of growth makes it important to understand every developmental milestone as a way to gauge each new stage of development in your child’s life.
