I have a 9 year old who is very easily distracted and has what you may describe as adhd traits. Her room is on the top floor of 3 stories. Never had an issue with her going to bed. However lately she’s taken to reading just before sleep - and sometimes other things like crafting etc. I don’t mind her reading for a half hour at all, but she’s ready much later into the night and she’s often exhausted the next day. I mostly don’t realise she’s still up. Shy of checking on her every 5 mins (becuase she here’s me coming anyway) what can I do!?
