You can help your children learn interpersonal skills by offering them opportunities to play with other children. By age three, children should have frequent chances to get together. Provide fun activities while you and other supportive adults remain in the background. This gradually helps children learn how to get along with others. If a child becomes frustrated with his playmates, encourage him to put his feelings into words. If there has been a particular problem between two playmates, help them see each other's point of view. Learning social skills takes practice. Don't be embarrassed or angry if your child acts in a socially unacceptable manner; it's normal for little children to learn from their mistakes as well as their successes. If your child still has difficulty playing with other children at age four, discuss your concerns with your family doctor or pediatrician.
