H.1.
This isn't a direct answer to your question, but if she is misin gout on all this sleep that her body is used to (becasue of the night time games she is playing) then I would veture to guess she is probably overtired and would suggest earlier bedtimes while everyone figures this out. If she's overtired from even a few nights of shorter sleep, then she probably struggles each night to settle down becausse overtired state makes it hard for a child to sleep. Plus, if you do earlier bedtimes, maybe you will get her to actually fall asleep by the time she normally does since she is taking that first hour to play games anyway. Once she's got it down, work back towards the normal bedtime.
