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 do not share or collaborate. 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 still developing essential skills such as imitation, independence, and social awareness.
