If the volume is already down after listening the lullaby during the beginning of the tracking, there is no way to have the same effect of gradual volume decrease with a min payback time other than to restart the tracking.
Add an option to reset the Lullaby volume timer even during the night.
If we wake up during the night and pause the tracking, we can reset the timer and listen to lullaby for the same period again before it starts lowering the volume.
