Growth and Developmental Milestones


Each child grows and gains skills at their own pace, but children usually move in a natural and predictable way from one milestone to the next. The Growth and development milestones look at five areas:

  • Physical growth,
  • Thinking and reasoning (cognitive development),
  • Emotional and social development,
  • Language development, and
  • Sensory and motor development.

A child may be advanced in one area, but behind in another. If your child keeps missing milestones or reaches a milestone but then loses that new ability, they may need extra support from a doctor or specialized programming.
