AbstractDespite Latinx grandparents' substantial involvement in child rearing, there is limited understanding of their child feeding practices. A survey examined 80 Latinx mothers' perception of Latinx grandparents' feeding practices and interaction with parents. Results showed grandparents engaged in positive feeding somewhat frequently and negative feeding somewhat infrequently. Mother–grandparent disagreement and grandparent–parent(s) communication on child feeding occurred at a moderate level of frequency. Mother–grandparent disagreement was associated with higher frequency of grandparents' negative feeding, while grandparent–parent(s) communication was associated with higher frequency of positive feeding by grandparents. Finally, grandparents' behaviors and practices varied depending on characteristics of grandparents, mothers, and children.
