Sleep problems impact the child’s current functioning and future development, as well as the family system (Byars et Simon, 2016; Sadeh, 2005; Stores, 2014). Thus, having appropriate sleep treatments is crucial. This article focuses on several behavioural sleep interventions in order to better assess their efficacy and their limitations. First, the literature reports methodological limitations important to address, which concern the lack of mid- and long-term follow-up to demonstrate their efficacy, and the lack of consensus on the ideal age to implement behavioural sleep interventions. However, different types of behavioural sleep interventions did not receive the same empirical support. This review is in the form of a critical reading guide and highlights two kinds of divergences between studies. On the one hand, these divergences are based on the benefits of the behavioural sleep interventions (in terms of the child’s behaviour and mood, and family functioning; Mindell, Kuhn, Lewin, Meltzer et Sadeh, 2006; Rickert et Johnson, 1988). On the other hand, the method of standard sleep extinction is reported as controversial: some studies proved its efficacy whereas studies express their doubts relying on ethical, moral and social frameworks (Blunden, Thompson et Dawson, 2011; Etherton et al., 2016).
