Sleep problems are a common concern of parents with toddlers. Various reasons have been put forward as to the possible causes and maintenance of sleep disruption. These have included neurophysical differences in the child, perinatal differences such as a long labour and depression and anxiety in the parents themselves resulting in adverse effects on the child's sleep patterns. However, recent research has indicated that a child's temperamental style may be a possible causal factor as to whether the child will present its parents with a sleep problem. This study, therefore, sets out to investigate the importance of temperament as a predictor of whether children may or may not have sleep problems. Environmental factors are controlled as far as possible by selecting toddlers with and without sleep problems from very similar environments. Case studies are also introduced to further illuminate other possible associated factors such as parental handling. The results from this study found significant differences in the temperament profiles of children with and without sleep problems. Children with reported sleep problems were more likely to obtain a 'intermediate high to difficult' profile. Various findings from a group of toddlers with and without sleep problems are discussed in this paper together with implications of the findings and recommendations for further research.
