This study aimed to investigate whether the pattern of associations among maternal control and discipline practices, perceived maternal warmth and hostility, and perceived sibling relationship quality differs across younger and older siblings. As previous studies examining the link between parenting and child-related outcomes generally recruited only one child in a family, we recruited two siblings growing in the same family. A total of 100 Turkish families with older (5.3 - 8.7 years) and younger siblings (3 - 5.5 years) participated in the study. Mothers reported their discipline practices, observers rated mothers' control practices, and siblings reported maternal warmth and hostility, and sibling positive affect and conflict. Results revealed that, for both siblings, (1) higher maternal positive control was related to higher perceived maternal warmth, in turn, associated with higher perceived sibling positive affect, and (2) higher maternal negative discipline was linked with higher perceived maternal hostility, in turn, positively related to perceived sibling conflict. Moreover, younger siblings whose mothers used higher positive control perceived their mothers as being less hostile yet there was no such association for older siblings. Overall, there were interesting differences between older and younger siblings although suggested associations were similar to a great extent across siblings.
