Example for a child that was on YouTube from 11:30pm - 1am on a given night:
Jim had a high quality day for the most part yesterday, 41m on Audible (audiobooks), 20m on YouTube, 20m on LinkedIn, and 15m on Hinge. However he had a late night YouTube session that went until 1am meaning he ended up spending 1h 33m on YouTube before he went to bed.
