Despite the assumption in early studies that children are monostylistic until sometime around adolescence, a number of studies since then have demonstrated that adult-like patterns of variation may be acquired much earlier. How \nmuch earlier, however, is still subject to some debate. In this paper we contribute to this research through an analysis of a number of lexical, phonological and \nmorphosyntactic variables across 29 caregiver/child pairs aged 2;10 to 4;2 in interaction with their primary caregivers. We first establish the patterns of use – both \nlinguistic and social – in caregiver speech and then investigate whether these patterns of use are evident in the child speech. Our findings show that the acquisition \nof variation is highly variable dependent: some show age differentiation, others do not; some show acquisition of style shifting, others do not; some show correlations between caregiver input and child output, others do not. We interpret these findings in the light of community norms, social recognition and sociolinguistic value in the acquisition of variation at these early stages.
