The current study investigated the general nature of joint attentional and conversational interaction in mother‐infant‐sibling triads. 9 19‐month‐old infants and 9 24‐month‐old infants were videotaped during 20 min of free play with their mothers and preschool‐aged siblings around a common activity. Analyses revealed that even 19‐month‐old infants were capable of participating in triadic interactions and conversations, and that the proportional frequency of both these measures increased with age. Triadic conversations were nearly 3 times longer and elicited nearly twice as many infant turns per conversation as dyadic conversations. Infants were more likely to join into an ongoing conversational topic than to initiate one themselves, and they were more likely to take a turn in those conversations if they were in a joint attentional state with the speaker. Infants were just as likely to respond to a comment or request directed to another person as they were to one directed to themselves, indicating reliable comprehension of language not addressed to them. These results suggest that the mother‐infant‐sibling interactive context differs in important ways from the mother‐infant dyadic context and that it is a richer language learning environment than previously supposed.
