This thesis aims to investigate different aspects of parental attitudes toward the concept of early childhood bilingualism. The theoretical part of the paper provides an overview of topics closely related to early bilingualism and language attitudes. It discusses the socio-cultural factors that influence the childhood bilingualism process. The first part also encompasses the types of childhood bilingual acquisition, as well as the basic information on family language policy. It also addresses the information on parental roles and attitudes in the process of childhood bilingualism. Apart from that, this thesis provides a brief overview of research conducted on the topic of childhood bilingualism. The third part presents the results of the research conducted by means of a questionnaire among 37 anonymous participants, who are parents of young children and are bilingual in English and Croatian language. Apart from investigating participants‟ attitudes and beliefs about the process of early acquisition of more than one language, the study also provides insights into parents‟ experiences of English-Croatian bilingual upbringing. The results show that the participants generally have positive attitudes towards early childhood bilingualism as well as positive experiences with this type of upbringing.
