This article is a comparative look at the cluster reduction patterns of English #sC onsets in three groups of children. Data from 40 monolingual, 40 Spanish-English bilingual and 40 Haitian Creole-English bilingual children were examined. While there were several similarities in the patterns exhibited by the three groups, there was a sharp contrast regarding /sl-/ clusters between monolingual children and the two groups of bilinguals. Among the predictions offered for reduction patterns in recent literature, 'factorial typology' of Pater and Barlow (2003 ) appeared to be the most successful.
