I'm surprised your study did not address, nor adjust for, children
who were in a daycare setting vs. those who were not. Women who must
return to work soon after birth often breastfeed less, or do not initiate
breastfeeding; Infants in daycare (especially of low quality and with a
high child/caregiver ratio) are more prone to SIDS, injuries, and exposure
to potentially fatal infectious agents.
I wonder if the results of your study might not have been very
different if the mothers' work and use of other care providers were noted
and adjusted for.

We appreciate Dr. Aronson's interest. In the study that produced the
data we used, mothers of infants who died were not asked questions about
day care, so we cannot examine her hypothesis.
