Honestly, they go to bed at the time the parent sets a routine after probably 3 or 4yo. My kids consistently go to bed at 9pm for school, 10pm on weekends/summer, and typically no problems going to sleep or waking up in the morning. It's been like that for years now. The time they did have trouble going to sleep at the right time is when they visited grandma for 2 weeks and had a wild and inconsistent sleep schedule the entire time. It took them about 2 weeks to adjust back to the normal routine. One hour adjustment from weekends etc is easy, but 2-3 hour adjustment is a huge stumbling block
