study of child-directed speech in dinner table interactions. This paper presents a corpus-based analysis of child-directed speech during Flemish family dinner table interactions. Specifically, we scrutinize parents ’ alternation between Standard Dutch and Colloquial Belgian Dutch, a substandard but supraregional variant of Dutch, when interacting with their children. In integrating insights and methods from variationist and interactional sociolinguistics, we pay attention not only to macro-social categories (such as the age of the children), but also to the micro-social and pragmatic context of the style-shifts (e.g. frames). As a practical consequence of this combination of course-grained quantitative analyses and fine-grained qualitative analyses, our study focuses in on a single case. We rely on detailed transcriptions of three hours of recordings for one Flemish household with four children (age nine months and four, five and seven years old). Our results reveal significant variation in the style-shifts of mother (age 35) and father (age 39) with respect to the four children, which can be interpreted against the background of comments made by the parents during a sociolinguistic interview that followed the recordings. Generally, our analyses allow us to provide a nuanced insight into the social meaning of the two language layers (Standard Dutch and Colloquial Belgian Dutch) as they are distributed across the speakers and situations in this family, as such revealing a link between the attested patterns of child-directed speech and the acquisition of sociolinguistic norms
