My dd1 is under diagnosis for Aspergers but she has an awful lot of characteristics. One thing we've read is that they don't sleep anywhere near as much as ... (us actually). dd1 has always taken hours to go to sleep and then gets up early etc. I perservered with still sending her to bed at what I think is a reasonable time given her age. She takes a minimum of 2 hours to go to sleep on a good day. We've tried all kinds of different things including music and reading time etc but in the end I've always said lights out music off at a certain time. She then takes ages to go to sleep. During that time she worries terribly and can really build small things into serious dramatic events. HOWEVER, when she does go to sleep late i.e. she's taken extra long to get off to sleep, she's distinctly tired the following day AND then finds it even harder to get to sleep the next night. At the same time reading some of the books seems to indicate that they simply don't need as much sleep and so possibly I should just leave her with her lights on happily reading her books until she's so tired she drops off quickly? Any advice?
