Despite our knowledge about the brainstem and the triple risk model, we know that this does not shed light on all
sudden, unexpected infant deaths. We know that a small number of babies die suddenly and unexpectedly before
one month of age and after one year of age. We know that many babies seem to have no known risk factors, and
others survive even with many risk factors. So, while we are making progress, there is still so much to do.
Until we can understand more about the mechanisms of death, until we can identify which babies are at risk, and/
or until we have achieved widespread saturation of safe sleep practices across all populations and socio-economic
strata, we must continue to do research and continue to deliver these life-saving messages, in hopes of saving as
many lives as possible.
