raised eyebrows recently when it released new guidelines saying that pacifiers
may protect against Sudden Infant Death Syndrome. The use of pacifiers for
sleeping infants has always been controversial, both in families and medical

pediatricians, suggesting pacifier use at sleep-time might actually save lives.
The Washington Post’s "New SIDS policy recommends pacifiers" was typical of the
headlines. What wasn’t reported was the fact that the announcement dismayed
