A Case Study On Care-Givers’ Language Variation, Proceedings of the Undergraduate Research Symposium (HUG 2018), Department of English Language Teaching, Faculty of Humanities, University of Kelaniya, Sri Lanka, P.66http://repository.kln.ac.lk/handle/123456789/21458The language used by the care-givers varies from one another and this variation affects on baby’s response towards each care-giver. Hence caregivers’ language variation directly effects on baby’s language acquisition in early childhood. Child care-givers’ interactions play a crucial role in child’s first language acquisition and early childhood development. This case study focuses on a nine months old baby who is in her preverbal babbling stage. Observations on baby’s interactions with the care-givers and collecting authentic speech samples of their interactions and baby’s response toward each care-giver were studied for three months. Results of this study manifested that the language used by each caregiver varies from one another and this variation makes a huge impact on baby’s responds as well. As this study only focuses on preverbal babbling stage, how this language variation influences on baby’s each stage of development would be a promising area for future studies.enCare-givers, babbling, early childhood development, first language acquisitionArticle
