This study of parents with their children demonstrates irregular and unpredictable grammatical features in their child-directed speech. The parents were observed quarterly in parent-child interaction with their oldest child beginning when she was two-years old, and with their younger twin daughters beginning when they reached two years. Language samples were transcribed and analyzed using CHILDES. The parents used grammatical speech with adults. A high proportion (8% to 32% per session) of their utterances to the children contained non-dialectal errors, primarily omissions of closed-class items. A typical example was ‘she a puppet’. The evidence suggests these parents were trying to teach their children language. Their implicit theories of language and learning led to a highy unusual variant of parentese.
