I guess bed is better. Sarung is just too traditional.

wow i almost forgot about the existence of sarong!!

u know what, i don't see the disadvantage at all - Just don't rock/swing too hard if you're worried.

sports or riding in a car would probably produce more impact than a nice rocking sarong...

plus yes, the motion helps with sleep, even as adults (u tend to fall asleep more easily in a moving vehicle)..

and; as for babies heads being rounder... could be true, i don't know

good to use sarung~

from medical perspective, the rocking motion of the sarung esp. with automated swinger may be an indication that affects baby's brain. and it's better for the spine development if the baby are allowed to sleep on a flat bed.

I would advise if possible try not to let the baby sleep in the sarung, train the baby to sleep flat on bed or side way. Based on my experience with my niece, she used to sleep in sarung and too depend on sarung, until she can't sleep at all in stroller(new stroller wasted due to this), she can't sleep when we hug/carry her, or anywhere else(sofa/bed/car). We can't go anywhere with her due to this habit that she has, no matter how we try to make her sleep and she seems so sleepy but just can't sleep because no sarung. I remember there is one time we need to travel in the car from kampung back to kl, she was crying non stop because she is so sleepy and only want to sleep in sarung, we even had to stop by a small mamak stall, put up the sarung/buaian and put her into it so that she can sleep. End up we spent 3 hours sitting at the mamak swinging the buaian, sigh... so now my baby boy i dont let him sleep in buaian at all, and he is so used to sleeping anywhere, either flat bed or rocker or carry him. This makes us much easier when we need to travel/bring him out to anywhere.
