Becos my dear son was introduce to sarong at my mother in law's house, so now, he seldom wanna sleep on his bed .. So no choice but to intro sarong also. Now, he sleep better in sarong and his head is more round!
Lucky, he is not dependent on sarong at nite. Cos when he sleep in sarong, the longest time that he can sleep is at most 1 and half hr though we get an auto craddle for him. He still need ppl to "yao" him then he will sleep. So i insisted him to sleep on his bed during nite time. He can sleep longer on his bed and normally sleep thru the nite.
