Parenting young children with and without Fragile X syndrome.

The purpose of this study was to examine maternal parenting styles across age-matched siblings using a within-family design, in which one child has Fragile X syndrome. Thirteen families participated; children were aged 16 to 71 months. Mothers completed several videotaped activities with each child separately as well as an interview. Mothers used a consistent, responsive style with both children, using the same degree of positive affect and warmth. Differences included using more behavior management strategies with the child with Fragile X and a conversational style of interaction with the sibling. Differences in approaches suggest the mothers adapted to the developmental differences between the children. The interview data supported these findings; mothers were aware of the changes made to accommodate the developmental differences.
