摘要：The paper presents two theoretical models of multilingual/bilingual development – Dynamic Model of Multilingualism (DMM) and Thresholds Theory (TT). The data from a case study of a successive Croatian (L1) – English (L2) bilingual development are presented in the light of DMM and TT. The author concludes that the mentioned models have a significant explanatory power but are not yet refined enough to present a multitude of aspects and interacting components in the development of successive childhood bilingualism.
