Dr. Sears’ guidelines don’t always reflect the consensus from medical science. Here’s how the two line up on some key points
Breast-feeding
WHAT SEARS SAYS
Breast is best, and babies should feed on demand and, if it’s O.K. with Mom, into toddlerhood.
WHAT SCIENCE SAYS
Little argument here–even concerning how long to nurse. The American Academy of Pediatrics agrees that frequency and duration are for Mom and baby to determine.
Responding to cries
WHAT SEARS SAYS
Parents should respond to all cries immediately, since excessive crying can damage the brain and lead to developmental disorders.
WHAT SCIENCE SAYS
Sears’ advice is alarmist. Allowing a baby to cry for brief periods will not cause brain damage.
Co-sleeping
WHAT SEARS SAYS
Bassinets that attach to the side of the parents’ bed are fine–but so, argues Sears, is sharing the bed with the baby.
WHAT SCIENCE SAYS
Bed sharing can be deadly. A sleeping adult can crush or suffocate a baby; the risk of SIDS increases as well.
