“…Sleep disorders are common in children with neurodevelopmental disabilities (NDDs), with a reported prevalence as high as 86% (Robinson-Shelton & Malow, 2016;Simard-Tremblay, Constantin, Gruber, Brouillette, & Shevell, 2011). In addition to affecting the children's physical and cognitive health and development (Turnbull, Reid, & Morton, 2013), sleep disorders may greatly impact on the well-being of both the children and their families (Adiga, Gupta, Khanna, Taly, & Thennarasu, 2014;Mörelius & Hemmingsson, 2014;Sandella, O'Brien, Shank, & Warschausky, 2011).
