I know I said I wouldn't post again but @Emmamoo89 did you even read the article you linked?
Like this part, right at the start:
SIDS has no known cause at this time but is believed to have multiple factors that lead to the death of the infant. The leading theory for the cause of SIDS is the Triple Risk Model, which is defined as three specific factors coming together to cause the death. The three factors are a vulnerable infant, in a critical period of development (2-4 months), and environmental stressors like exposure to cigarette smoking during and after pregnancy, soft mattresses, bedding and objects in the bed, co-sleeping, etc. When these three factors overlap, the incidence of SIDS increases.
It specifically mentions bedding & objects in the bed as risk factors.
The point you appear to be focusing on is this:
Recently a new research studyy* was released online, with findings that could be the key to determining what an underlying vulnerability is in babies that die from SIDS, despite being in a safe sleep environment
Which is a possible blood enzyme issue and is specifically talking about babies who die from SIDS despite being in a safe sleep environment.
The article concludes by reminding of the importance of observing safe sleep habits.
You are not only wrong, you are irresponsible to try and twist this to 'it's a chemical issue; nothing can be done to prevent it'. I've tried not to personalise this but it really makes me so angry that you can refute science & medical evidence & falsely present alternative causation.
