If there are children in different ages around the child, it will feel more like a big family to him. Most time, infants enjoy watching toddlers playing, then infants will try to imitate how toddlers play; in fact, imitation between children is usually better than any other education methods. Older children usually like infants, and they always try to imitate adults to take care of their infant friends.
