Doorway Swing

I have the Graco Bumper Jumper, but I find nothing in the instructions online or do not swing it. I know this is not the sound, but designed for my baby likes to push a swing with the baby inside. I want to be sure there is no risk of letting go of the door. I do my best to keep my child away and not leave the jumper to push a swing, but now the baby is how to swing slightly in itself.

Do you have babies in their tracks riders?

So when I was 11 I was babysitting for one month to 6 years (do not ask me why his parents let me see lol, I never let a care for my 11 years baby) Anyway, he had a jumper. I pushed him as he was on a swing, then out of nowhere stupid jumper from the ceiling and it crashed to the ground. It was fine, just a little shaken. I do not know if it was the rider or the parents didn't quite sure ... but I wouldnt push just in case??? But who knows, who was made a while ago, they may be different
