My 8yo for several months now struggles to sleep through the night. He takes an hour or 2 to fall asleep because he worries that he won't fall asleep in the first place. He needs his night light on all night because he's scared of the dark and the other problem is he sweats all night and this wakes him up because his Pyjamas will be completely soaked through. I have to help him change every night once or sometimes twice. Sometimes his sheets are so soaked he has to come in to bed with us. Really need some advice if anyone else has experienced this. He wears light pjs, usually shorts and t shirt even in the winter and heating is always off in his room. We even have the window open a crack. Not sure what else to do.
