DD is 3yo, and she goes to bed between 7:30 and 8pm (depending on what we have been doing, dinner time, and what we are doing next day), has a story and then settles down on her own. She does soemtimes read to herself after I ahve left, but generally not for long.
At weekends bedtime is sometimes later - again depends on what we are doing. At a wedding evening party on Saturday so who knows when bedtime will be!
