The present paper examines the child's use of deictic gestures in the process of topical co-operation with his father. The method for the study is qualitative and data driven conversation analysis based on examining communicative practices in natural settings. The database is composed of videotaped naturalistic picture book conversations between the child (at the age from 1 to 2 years) and the adult. For the current paper, the sample of data is transcribed and analyzed focusing on the sequential organization of the participants' verbal and nonverbal action (gestures, gaze, vocalizations and adult's speech) focusing the analysis on referential actions in the sequence in which the topic is extended from the referent in the picture book to the referent outside the book. More specifically, the focus is on how both the verbal and nonverbal referential resources reveal the participants' orientations in the on-going interaction, creating a shared referential focus.
