SIDS however is probably genetic and little we do has made a difference (for example, when I was a baby the advice was to sleep children on their stomachs - it's literally the opposite now)[1]
Like cardiovascular diseases, it's genetic but it's still in your interest to reduce risk factors (like smoking, which is apparently a risk factor both for heart trouble and SIDS.)
