Verified step by step guidance

1. Understand the concept of cooperative play, which refers to children playing together with shared goals, rules, and interactions, rather than parallel or solitary play.
2. Recall developmental milestones related to social behavior in early childhood, focusing on when children start to engage in more complex social interactions.
3. Recognize that infants around 6 to 8 months old typically engage in solitary or parallel play, not cooperative play.
4. Note that by 18 to 24 months, children begin to show interest in others but mostly engage in parallel play rather than true cooperative play.
5. Identify that around 3 to 4 years old, children typically develop the cognitive and social skills necessary for sharing and cooperative play, making this the typical age range for such behaviors.
