A strong association between early vocabulary comprehension and production has been shown in typically developing children (TD), and there is robust evidence for a lexicon-grammar association. These relations have been inconsistent in children with Down Syndrome (DS). In this study, ten Spanish-speaking children with DS were observed for vocabulary comprehension, production and initial morphosyntax using a parental report, the Down-CDI. Results showed high individual differences and developmental patterns were not similar to the literature of children with TD. The relation between vocabulary size, composition, sentence length and complexity was inconsistent. Thus, some developmental patterns of TD children are similar in children with DS. There is an association between grammar and vocabulary at the general level, but not within specific components.
