We start the bedtime routine around 8. Our 2 year old is in bed around 8:30. I will also say that she thrives on routine, so the few times that someone else has been with her to put her to bed (when she stayed with grandparents when her baby sister was born, or when she spent the night with her other grandparents), the 8:30 thing didn't always happen. Her routine was off, and she just had to "run down," so to speak.
