Babies born by Caesarean section have dramatically different gut bacteria to those born vaginally, according to the largest study in the field. The UK scientists say these early encounters with microbes may act as a “thermostat” for the immune system.
And they may help explain why Caesarean babies are more likely to have some health problems later in life. The researchers stress women should not swab babies with their vaginal fluids – known as “vaginal seeding”.
How important are gut bacteria?
