DS2 (3) goes to bed the same time as DS1 (5.5), which is usually ~8-8:30, though he's often up till ~9. He rarely takes naps, and is usually up by ~7.
Tell me about your 3 1/2 year olds sleep schedule...please! - Page 2
ODS is in K this year so we are much more careful about bedtime, in a good way. DD is almost 3 1/2 and hasn't regularly napped in over a year. She usually is asleep by 7:30-8 pm and is up at 6:-6:30 a.m. Once a week or so she'll add an hour or two to her sleep. She doesn't SSN. She will wake up once and walk down the hall and crawl into bed with me and go back to sleep within a few minutes.
