The discursive practices between family members convey important pragmatic meanings. This study takes attitude resources in Martin's Appraisal Theory as the theoretical framework and uses daily parent‐child conversations as the source of corpus to analyze the distribution of different evaluation resources in the communication between parents and children and to discover the personal identities parents construct. The results show that affect resources in parents' discursive practices takes highest frequency, while the appreciation resources of the lowest frequency. In addition, parents construct three different aspects of their personal identities: personality, stance and relation identities with the appraisal system. The study aims to improve identity management of family members so as to provide pragmatic solutions to the existing problems in parent‐child communication.
