I just skimmed through Dr. Sears' book, SIDS: A Parent's Guide to
Understanding and Preventing Sudden Infant Death Syndrome. See Ch. 7, "Step
Four: Breastfeed Your Baby"  He points out there will never be a controlled
study that proves BFing directly protects against SIDS. There are ethical
issues with requiring mothers to NOT breastfeed in order to form the
required control group. Information comes from prospective studies and
common sense. 

Quoting: "A study from New Zealand shows that SIDS was three times higher
in babies who were not breastfed."  and this:  "Of the eighty-six babies
she studied ... only three were breastfed; and this occurred in a country
with a particularly high incidence of breastfeeding."

Often, what appeared to us to be evidence of the protective effect of BFing
was discounted by researchers as being more related to non-smoking, moms
who were of higher socioeconomic levels, moms who had prenatal care, etc.
than to BFing.

Dr. Sears observed that the NICHD study showed higher SIDS rates among
formula babies.
He also mentioned the "AVON Study" (don't have the cite) that there was a
lower rate of SIDS among BFing babies. So he backs up his conclusions with
observations noted in these studies, common sense reasoning based on the
protective effects of the milk itself, and the physical activities of
BFing, ie: arousability.

I have no $$ interests in any of the above - they are from my personal
reference library.
