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

It could cause injury to your baby if he falls out of the hammock or internal brain bleeding from vigorous swaying. http://www.channelnewsasia.com/news/singapore/improper-use-of-child/2222398.html “One five-month-old baby fell out of a traditional sarong cradle after his mother left his side briefly. Even though the cradle was only half a metre from the ground, the baby suffered a serious head injury due to the greater momentum of falling from a springy cradle,” she said. Though cooling, it is not advisable for babies to sleep in as there is a higher SIDS risk. To minimise the possibility of Sudden Infant Death Syndrome (SIDS), do let your child sleep on a firm surface with just a fitted sheet. Instead of soft pillows, use a folded breathable muslin cloth and try out a baby sleeping bag in place of a blanket. http://ph.theasianparent.com/is-it-safe-for-your-baby-to-sleep-in-a-duyan/
