This paper draws attention to the key role of a caregiver's bilingual language practices in the process of language shift. It argues that certain multilingual practices actually discourage children's multilingualism and devalue the language at the same time as they provide preverbal children with direct input. The analysis is based on data collected in Russophone urban families of ethnic Kazakhs. Drawing from work on registers and footing, the paper demonstrates that in these families the Kazakh language, while quantitatively prevailing in caregiver's speech, systematically co‐occurs with Baby Talk – a specific register directed to infants and toddlers in their preverbal stage. The metapragmatic typification of talking Kazakh to non‐agentive objects‐of‐minding, and talking Russian to autonomous social agents, suggests that language practices envision expert members of the local community as Russian speaking. This ideology sustains the ongoing language shift to Russian despite families’ aspiration to raise Kazakh‐Russian bilingual children.
