DD is 16 months old, and goes to bed when she's ready. Usually somewhere between 7-8pm, and it absolutely depends on how many/how late her day sleep(s) have been. She ideally has just one day sleep, at 12, for 1-2 hours, usually closer to 1 hour. But there are days when she passes out early, then needs another sleep, or we're out doing something exciting and it's late. Those days suck.
