Childhood milestones age 3
At 3, your child is continuing to develop physically and make huge progress in his or her ability to speak, play, learn and interact with others. Your child will develop by experiencing the world around him or her through exploration, and he or she will develop an increasing self-awareness.
This guide gives some idea of what to expect by the time your child reaches his or her third birthday, but it's important to remember that children don't develop according to a fixed timetable. The speed at which children mature can be highly variable and your child may reach some stages earlier or later than others of the same age without there being reasons to be concerned.
Age 3: Physical development
By the time your child reaches the age of 3, he or she should be quite steady on their feet and able to run easily. He or she should be able to stand on tiptoe while walking and turn while running and pulling toys. Your child should now be able to walk up or down the stairs with one foot on each step and should also be climbing well. At this age expect your child to be able to pedal a tricycle.
Age 3: Cognitive and language skills

Expect your child to be able to name most familiar objects and understand words such as "in", "on" and "under". He or she should understand the concept of what "two" means.
