The paper analyzes the data collected during interviews recorded with Polish-French and Polish-English-speaking bilingual children living in Poland, aged from 4 to 8. The task given to the participants was to describe spatial situations in a series of images by answering the researcher’s question where is X? The answers were supposed to follow the BLC (Basic Locative Construction) pattern. The given locative constructions were then transcribed in CHAT format and analyzed in order to find out what the children’s repertoire of locative prepositions in both language groups is, if the prepositions follow the order of acquisition for both French and English and if any discrepancies in the use of prepositions might result from interlingual transfer.
