Parallel play is a type of play where children play alongside each other but do not directly interact. This behavior is common in toddlers and preschoolers, typically occurring around ages 2 to 3. During parallel play, children may use similar toys or engage in similar activities, but they focus on their own play without sharing or collaborating. This form of play is important for social development, as it allows children to observe and learn from one another. While they may not be interacting, they are developing skills such as imitation, independence, and self-regulation, which are essential for later cooperative play.
