Starting at birth, your child will begin to reach milestones in how they play, learn, act, and speak. Examples of milestones include taking a first step, smiling, and reaching for a toy.

Milestones fall into 6 major areas:

  • Communication: how children use language – speaking, listening and understanding
  • Gross Motor: how children move their arms and legs
  • Fine Motor: how children use their hands
  • Problem Solving: how children think and solve problems (sometimes called “cognitive skills”)
  • Personal Skills: how children help take care of their own needs, like feeding and dressing.
  • Social and Emotional Skills: how children manage and express their emotions and relate to others.
