Children go through different developmental stages as they get older. These stages are usually a norm for children. Some children may be slower to reach the stage, but should not be excessively behind other children of the same age. If a child is not reaching developmental stages at the right time, the pediatrician should be made aware of this, to make sure there are no developmental issues. Most child development specialists want to see that certain skills have developed between the ages of two and five.
Two Years Old
By two years old, children are considered toddlers and should have made some advancements and learned a variety of things. At two years old, children should have several movement milestones, which include being able to walk alone, moving toys, climbing onto furniture, able to kick a ball and walking up and down stairs while holding onto something. In terms of vocal abilities children should be able to say small sentences and use up to 50 words. Repeating words heard in a sentence and naming body parts is also normal at this age. At two years old children may also have some separation anxiety when leaving parents.
Three Years Old
At three years old, children should have more language and movement abilities. Parents and child care providers will also start to notice more of the child's personality coming out. Children should now be able to leave parents without anxiety. They may also start to focus on asking why things are done. They will be able to ride a tricycle, as well as kick and run. They should be able to speak in short sentences using "I," "me," "you" and "we," as well as have a vocabulary ranging from 250 to 300 words.
