There is an expanding interest in Sleep medicine as a recently developing branch of medicine attracting a lot of researchers with repeated trials to investigate sleep as a phenomenon its regulation, functions and its relation to physiological functions as respiration, cardiovascular system and hormones. Sleep in children has not been skipped by many of the researchers including different surveys trying to discover normal sleep patterns in children as well as disorders more likely to be seen in different age groups. Different surveys which have been done encourage the need of research in this area with the aim of arousing the importance of sleep in children as needed for normal brain development as well as growth. In Egypt, sleep medicine is still considered a luxurious part of medicine due to high costs of its investigation and the rarity of doctors practicing it. Apart from this, in children we do not have any visualization to common sleeping habits and disorders (how do our children sleep, normal and those with psychiatric problems). Due to the above reasons, it was of interest to investigate sleep habits among children. Subjects and methods: 30 children suffering from different psychiatric diagnosis were age and sex matched with 30 control group. Both were assessed using; a full psychiatric sheet, Stanford Binet Intelligence test where IQ less than 70 was excluded together with organicity. A child self-assessment sleep Questionnaire is administered to the child, and the parents’ evaluation of their child sleep was done using translated version of Child Sleep Questionnaire. Results: Co sleeping is very high among Egyptian population whether with parents or siblings, whereas transitional objects is not a popular practice. The clinical sample showed significant difference in symptoms suggesting obstructive sleep apnea and excessive daytime sleepiness. Bedtime resistance as well as sleep anxiety scored high in the clinical group, whereas parasomnias was seen to be high in both groups. Parasomnias, sleep anxiety were found more in girls while sleep disordered breathing scored higher in boys. Conclusion: Sleep problems need to be evaluated in children with psychiatric problems so as not to miss treatable problems.
