The phonologies of three English-speaking children at approximately two years of age are examined. Two of the analyses are based on published studies; the third is based on observations and recordings made by the author. Summary statements on phonemic inventories and on correspondences with the adult model are presented. For the third case, fairly detailed phonetic and distributional data are also utilized. The paper attempts to draw conclusions about typical difficulties of phonological development at this stage and possible strategies used by children in attaining the adult norms. (Author/JD)
