Which of the following is an effective way to encourage social interaction among infants and toddlers?

Encouraging shared materials and cooperative play is an effective way to promote social interaction among infants and toddlers because it fosters a sense of community and teamwork. When children engage in cooperative play, they learn to communicate, negotiate, and problem-solve together. This approach allows them to practice social skills such as sharing, turn-taking, and empathy. Additionally, shared activities provide opportunities for positive social experiences, which are critical for developing healthy relationships and social competence during early childhood.

By facilitating interactions through shared materials, caregivers can create an environment that supports social development and encourages children to work together, thus enhancing their ability to form friendships and understand social cues.
