DS suddenly seems to need much less sleep - going from 11 hours a night to seeming to need closer to 9.
He's up OK in the morning, behaving well, and very active -swims at least once every day, leaves for school before 8 and out until 3.30, plus afterschool sports a couple of nights a week.
But not going to sleep until 9, up at 6 prompt. Is that normal for his age? He's in bed relaxing from 7.30, but can't sleep.
