Hi. I am currently sat up watching my nearly 5 year old sleep because he is always exhausted despite sleeping seemingly well (cannot cope with school, 30 mins swim and nothing else in the morning = 2 hour nap, this type of exhausted). Doctor isn't sure if it's some sort of parasomnia or sleep related seizures disrupting his quality of sleep, or something completely different. There are no known nutrient deficiencies, he has had numerous blood tests to rule these out. For context, I suspect he has some sensory issues and there are definitely some fixations with interests, he is very sensitive to stimulation but not diagnosed as ND.
Please, could anyone tell me:
Has anyone experienced either of these?
Is it common for children to be rubbing the mattress/sheets/their own body with their hands and feet in their sleep?
Is it common for children of this age to sit up / eyes open / look around and go back to sleep but have no recollection?
I'm not sure what I'm supposed to even be looking for or how to help him. It's been going on years but I've always been told he's just a tired child and I've kept pursuing it (and been laughed at by professionals more than once, sadly).
Thank you.
