jolene, suika: SAME here! I was about to post and ask mummies here. my boy also has the same problem of flipping at night. my boy can flip from back to tummy but can't flip back. so at night while he sleeps, he tends to flip sideways or face down and continue sleeping. then he can't sleep for long and cry... dunno whether it's the awkward position or that he can't breathe (!!) so scary. anyway, hb and me been flipping him back the whole night the last 2 nights. so tiring! barely had enough sleep already with the feedings, now he adds in the flipping. we never used sarong. so I dunno how to stop him from flipping. maybe we have to tahan until he knows how to flip back? what do you all think?
