Getting your child to do things

I'm assuming you mean Neuro Divergent (as diverging from what's Typical) - and no. Because according to psychoanalysis, the Typical (non-divergent) brain is wired to work quite well with language/words and use nuance and pretence to socially engage. So one can actually talk themselves into a thing. 

Most autistics and others who are Divergent, diverge specifically from this sort of brain 'wiring' and don't use language or words the same. For this reason, adverts might not make sense and one might not have "normal" social skills. To the same extent, they have trouble with lying, they might not appreciate social pretending and may have to learn the reason to do so when older.

It's good for children to sleep, though. I found reading my son fiction helped. We read classic longer storybooks which didn't have pictures (which are distracting), to help him engage his imagination, which would lull him into a restful slumber. The ADHD, Autistic and even dyslexic mind has been associated with Monotropism. Which can mean intaking a lot more than Typical and operating at a fast pace, difficult to turn off. For this reason, it's good to give your child something to engage but isn't personal - fantasy and escape which they can immerse into. 

There's a load of other reasons a child might still be awake though. I always recommend a halogen light or a salt lamp at least an hour before bed and even black out curtains. Blue light emitting LEDs wake us back up. lightaware.org
