The aim of this study was to determine what information pertaining to Infant Sleep Disturbance (ISD), and intervention for it, are portrayed in two forms of popular parenting resources (books and websites). Through using a content analysis of the two forms of parenting resources ten categories emerged and conflicting text data were identified. Twelve questions that emerged from this conflicting data were then investigated through evidence-based literature reviews. The findings showed that although some parenting resources claim detrimental effects of infant sleep interventions no research study has concluded so. This study highlights the need for evidence-based information being presented to parents and it also highlights the need for a continuance of ongoing research into interventions that combine both behaviour and attachment theory.
