Frequency of sibling literacy interactions were examined in 134 families with at least two children, where at least one of the children attended school in grade one to grade four. Parents in the majority of families reported that their children read together on a regular basis without a parent present. This held across various demographic constellations including gender of the older child. However, children from families with three or more children were less likely to read with their siblings. Implications for parents and teachers are discussed.
