Sleep problems and social–emotional (SE) problems are common in preschooler children and may be affected by culture. However, little is known about the link between sleep and social–emotional problems in non-Western countries. This study aims to compare sleep problems and their association with SE problems in Turkish children with either typical development (TD) or neurodevelopmental delay (NDD). In this case–control study, children with NDD ( n  = 126) and children with TD ( n  = 102) were included. Parents completed the Children’s Sleep Habits Questionnaire (CSHQ), and the Ages and Stages Questionnaire: Social–Emotional (ASQ:SE). More than half of the TD and NDD groups had sleep problems when assessed by CSHQ (54.4%, 72.2%, respectively). The correlation between CSHQ and ASQ:SE scores in the NDD and TD groups was r  = 0.44 and r  = 0.352, respectively (both p  < 0.001). Children who slept less than 9 h had lower ASQ:SE scores in the NDD ( p  = 0.003) and TD group ( p  = 0.023). In the TD group, those who slept after 23:01 h had lower ASQ:SE scores compared to early sleepers ( p  = 0.04). Multivariate analysis revealed associations between SE problems and male gender, lower family income, bedtime resistance, and shorter sleep duration in the NDD group. In the TD group, male gender, sleep onset delay, sleep duration of CSHQ subscale were found to be associated with SE problems. Sleep problems were identified in more than half of all preschooler children, regardless of developmental delay, and were associated with increased SE problems. Interventions to correct sleep problems may have a positive impact on children’s emotional development.
