My DD hasn't had a day sleep since before she was 2, can't remember exactly when but it has been a good few months now. She goes to bed at 6pm and starts the day around 7:30am. If she ever does happen to fall asleep in the afternoon than she is up past 9pm but sometimes it is needed so I just go with it.

ETA: it was an adjustment at first, trying to keep her occupied for the entire day without a break but I prefer it now. We never have to worry about organising things around day sleeps and she goes down for bed (and sleeps better overnight) super easily.
