help!

I recently discovered bouncing on the exercise ball instantly calms my LO and puts her in like a trance lol and she'll usually fall asleep. Which kinda makes sense, I was on the exercise ball for most of my 2nd and 3rd trimester lol. Only thing is I can't bounce on that thing 24/7 to calm her lol. Does anyone know of anything that replicates that bouncing movement? She hates the swing and rock n play lol 👍🏼. She is 7 weeks, so one of those like door bouncer things aren't an option 😞 thanks mamas!
