Long story short, DS age 9 has always struggled with sleep (both falling and staying asleep). He’s currently only getting around 5/6 hours of broken sleep a night and is exhausted. We’ve tried everything imaginable to help him except melatonin. In complete desperation (and on the advice of a local ASD charity) I ordered some 1g melatonin gummies from Piping Rock in the US (we cannot get melatonin prescribed on the NHS here) but I’m really worried about giving him something I’ve bought on the internet. Has anyone done this?
