The asthma-C-Section connection

Not that we usually have a choice in the matter, but if you do, here's a reason not to schedule a C-section unless you need one:  Babies born by cesarean are 80% more likely to develop asthma by age 8 than children delivered vaginally, says a new study published in Thorax.  Kids whose parents have asthma are even more likely to become asthmatic if they're delivered by C-section.  Researchers believe that infants are exposed to microorganisms in the birth canal that help prime the immune system.
