From the start, babies want to explore their world. They are eager to move their eyes, their mouths, and their bodies toward the people and objects that comfort and interest them. They practice skills that let them not only move closer to desired objects, but also move desired objects closer to themselves. As they grow, children's determination to master movement, balance, and fine-motor skills remains intense.

Age Milestones

The first year

A baby begins learning the basics of self-movement and begins to master the skills needed for hand-to-mouth coordination and holding objects.
3 months

Most infants begin to:
  • Raise head slightly when lying on stomach
  • Hold head up for a few seconds, when supported
  • Hold hand in a fist
  • Lift head and chest, while lying on stomach
  • Use sucking, grasping, and rooting (holding tongue to the roof of the mouth) reflexes
  • Touch, pull, and tug own hands with fascination
  • Repeat body movements, and enjoy doing so
  • 3 months
    6 months

    Babies are quickly becoming stronger and more agile. Most begin to:
  • Roll over
  • Push body forward and pull body up by grabbing the edge of a crib
  • Reach for and touch objects
  • Reach, grasp, and put objects in mouth
  • Make discoveries with objects (for example, a rattle makes noise when it is moved)

  • 6 months
    9 months

    "Child-proofing" becomes important as babies get more mobile. During this time most begin to:
  • Crawl
  • Grasp and pull things toward self
  • Transfer objects between hands

    12 months

    By this time, most babies can:

  • Push and pull objects
  • Seat self in a child's chair
  • Walk up and down stairs with aid

  • Shift marker or any drawing or painting tool from hand to hand and draw strokes

  • 2 years
    3 years

    Children become more comfortable with motion, increasing speed, and coordination. Most begin to:
  • Run forward
  • Jump in place with both feet together
  • Stand on one foot, with aid
  • Walk on tiptoe
  • Kick ball forward

  • Children are able to manipulate small objects with increased control. Most can:

  • Walk on a line
  • Balance on one foot
  • Push, pull, and steer toys

  • Drive pegs into holes
  • Draw crosses and circles
