Mine have only both just dropped day naps at nearly 5 and 3 1/2 ( I know, freak children). Prior to this they were going down around wish and not falling asleep til 8:30 sometimes, but now that they aren't sleeping they are in bed by 7:30 and generally asleep by 8 and they sleep til 7. We have always tried for a 7oclock bedtime but as they have gotten older its gotten later but I am actually glad now that they are going to bed earlier at 7:30 and sleeping through til 7 rather than taking ages to go down and then waking up at 6-6:30. They still have a quiet/rest time in their rooms for an hue each day that they don't sleep. (DS still occasionally naps)
