I need to get better about narrowing down a bedtime for the girls. They have been going to bed between 7:30 (for my youngest) and 9:00pm. Last night it was 8:50pm, the night before it was 8:00pm. I'm not super strict as in I want them down at 8:00pm on the dot, but I think at least within 15-20 minutes is what I should aim for.

Does your LO go down at the same exact time every night? How lenient are you with it?
