Agree to most above. I have a kid who has to read at night. I understand. I have to read at night. So I make sure reading time is built into every night- weekends included. I usually head in about 10 minutes before his lights out time and we flip through his book together to find a good page break or chapter end coming up that can be his stopping point. The only "punishment" he's ever received for reading past that point and staying up late was to have to stop reading mid-sentence and go to bed when I caught him. The next day when he complained about being tired, I reminded him why that might be.
