DD has a book light she uses when DS is ready to go to sleep and we turn the lights off. I avoid letting her use the iPhone at night because it really keeps me up so I agree it adds to the problem; I sometimes let her use my kindle with its light. Yes, sometimes she's up til ten but mostly she'll feel the need for sleep (early riser) and let the story go til morning. Had a hard time last night in the middle if the exciting conclusion of Prisoner of Azkaban! I helped her find a good chapter break with no cliff hanger
but mostly she's in charge. We do follow a fairly early bedtime because we know she'll want a good chunk of reading time (and life is generally much happier all day long when she has a good book she's enjoying even just at night.)
