The contact with members of her linguistic community since the first days of a child s life is of fundamental importance for his/her language development. Assuming the social-pragmatic perspective, mother-infant linguistic interactions can be considered as one of the bases of the initial language development. Assuming that mother speech has a fundamental role in the process of child linguistic development, this longitudinal study aims to analyzing characteristics syntactic and semantics of maternal speech directed to children (MSDC), identifying transitions of mother-child communicational frames (attentional, conventional and symbolic). Syntactic and semantic aspects of maternal speech were analyzed and the trajectories of those frames throughout the development were identified. Four children, two boys and two girls, and their mothers were observed longitudinally from 13 to 24 months of age. The instances of maternal speech directed to children were identified, transcribed and classified in affirmative sentences, negative sentences, imperative sentences and interrogative sentences. The transitions from attentional to symbolic mother-child communication frames were identified. The percentage of maternal affirmative sentences was predominant in all dyads and the negative sentences, although, showing specifics tendencies of trajectories, were less emitted by mothers. MSDC showed transformations following the baby s development. Different types of maternal sentences presented diverse patterns of development across time and in the four dyads. Speech related to the context increases linearly across time. Babies´comprehension and production vocabulary showed a linear increase across the 12 months observed, and the substantives words were predominant. The mean of engagement in all dyads was 76%. The percentage of time in attentional and symbolic frames showed a linear relation with the increase of baby s age in all dyads. Some correlations, in all dyads, were identified: babies´age to comprehension and production vocabulary by children; the infant comprehension to infant production vocabulary; and maternal speech related to the child was correlated, negatively, to maternal speech related to the context. The study brings a contribution to the literature on maternal speech and initial language development with data from a Brazilian context
