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

Maybe it's not true as i think there are different mode on the swinging part. Maybe just low speed will do. If it's true think Sg will ban it liao. As for me i never use the auto one. I use the traditional one and i swing it myself. I prefer the old type. Swing slowly and pat pat his butt. Love it.
