Have the same swing, but mine doesn't auto shut off.
+1there are other options for the same swing-not bunny, but other animals/designs (snugamonkey maybe)...maybe those are available without the auto shut off?
Never knew you can leave it on use it. Always thought that when you put baby in seat the motor needs more electric to run or something like that...
I would also think when you hold the swing to put the child in you stop the motor for a few seconds
