Could this be the key to passing on a mother’s bacteria to her Caesarean-born baby?

Babies born vaginally get exposed to important bacteria as they pass through their mothers’ birth canals — bacteria that helps their immune systems develop. But babies born by Caesarean section miss out on some of these beneficial microbes, which some worry may leave them more susceptible to health problems down the road.

Researchers wanted to test whether it’s even possible to transfer mothers’ vaginal bacteria to babies born by C-section, and published on Monday their small, proof-of-principle study in the journal Nature Medicine.
