Recently, an Australian study identified a possible biological marker for SIDS. However, it is essential to note that many new headlines misrepresent and overstate the study’s findings. The study only reports on a possible biological marker that may be linked to some SIDS cases. The study also used a minimal sample size and overlapping results. There is no test for the biological marker, so parents cannot have their babies tested. However, practicing safe sleep habits is still very important.
