At age three or four years, your child might be very skilled at interacting with peers, especially if they have siblings close to their own age. But even if they had little experience getting along with other children, that doesn’t automatically, place them at a disadvantage. A child who is a beginner with peers can catch on quickly, while some old hands might need to unlearn behaviors (such as toy snatching) that worked in a previous setting, but not anymore.
In addition to his past experiences, a child’s temperament plays a big role in how easily he gets along with other people. A moderately active, outgoing, cheerful child often has a relatively easy time. A child with high energy and strong impulses often has more negative early relationships until he develops some measure of self-control. A cautious child might spend lots of time observing from a distance, until he’s more comfortable in a given setting. Even then, he might choose to have one or two friends, rather than several. It takes parents who know their children well, and teachers who can work with a range of different children, to make the preschool experience positive for every child.
