Another way parents can provide models that are just within the child’s ZPD is by providing an extension of the child’s utterance. Similar to expansions, extensions provide the child with additional information to accompany their own utterance. Unlike expansions, extensions do not require the parent to say the child’s utterance back to them. For example, if the child said “Baby.” while holding a bottle the parent could say, “She is hungry.” or “Let’s feed her!”. This provides the child with information that is related to the initial utterance, and continually engages the child in their interest while providing an utterance that is slightly above the child’s current production level (Paul & Norbury, 2012). This act of building up a child’s utterance can be used together with breaking down their utterance to provide them with even more information.
