DS is 19 and has always tended to go to bed very late but it’s now getting a bit ridiculous since we went into lockdown. I don’t think he’s going to sleep till 4 or 5 am, sometimes later then sleeping till early afternoon. I’ve tried talking to him about importance of good sleep patterns, wakening him up early etc but doesn’t seem to work. Should I just leave him to it? I’m a very light sleeper so he’s often going to the toilet about 5am and will say he’s woke up for the toilet but he’s actually just going to bed. Arrrgggg
