Is it true that using the automatic swinging yao lan (sarong) can cause damage to the baby brain due to constant swinging motion?

I'm using Yao Lan for my girl till she is age 3 when she know how to climb out from it. I did not just automatic Yao Lan. I did swing lightly to allow her to sleep deeply. She is perfectly fine. Just bear in mind even if you are not using Yao Lan, you also not advisable to swing her high up and down especially some elderly like to play with them.
