Birth to 3 Program: Child Development

Developmental milestones are skills that children gain as they develop and grow. These skills fall into four areas:

  • Language/communication
  • Social/emotional (forming relationships and understanding and managing emotions)
  • Cognitive (learning, thinking, and problem-solving)
  • Movement and physical development.

Every child develops at their own pace. However, sometimes a child may not reach a milestone by a certain age. If that happens, supports or services from the Birth to 3 Program could help boost their development.

Below are some tools you can use to track and understand these milestones.
