My kids normally wake up between 7:00-7:30, but they aren’t allowed to get is until 8:30. Yesterday they slept until 8:30 & I was awake, so nothing changed to them. They just thought they just slept in. I changed the clocks after lunch when they weren’t paying attention. They probably laid in bed awake an extra 30 minutes last night, but the time they actually fall asleep is always changing anyway. They never noticed they lost an hour.
