it's so ridiculously early to be sorting out next years' accomodation, isn't it?
Noah - not sleeping cos of noise/rubbish curtains letting light in (ear plugs/eye mask) or stress (calming music/white noise app/mindfulness app)? Generic advice is don't eat too late in the evening, cut out or down on caffeine (esp after lunchtime), switch off devices a couple of hours before bed (yeah right, whenever did a teenager not have a device in their hand
), regular routines - so get up at the same time every day, go to bed at the same time every night. Also lists - everything they need to do in a brain dump, then order according to deadlines, then colour code (as an alternative to destressing with colouring books "they've for babies, don't be ridiculous mum!"). And minimal alcohol which disrupts sleep. Any use?
