How long would you shake your baby (< 10months) in the sarong/ yao-lan, to encourage her to sleep?

I carry my 2 months old and rock her to sleep with a bit of bouncing motion (resembling a car ride) for about 10-15 mins everyday. At least next time we still can travel or go out when she needs a nap she just need me to be there. I'm her portable yaolan 😂
