In a study of nearly 400 breastfeeding mothers, researchers find links between directly feeding the child and a more diverse microbiota, compared to milk from pumping.
Doctors report that a regimen of hormones, an antiemetic drug, and pumping gave the woman enough milk production to feed her baby exclusively breastmilk for six weeks.
Analyzing the gut microbiomes of children from birth through toddlerhood, researchers tie compositional changes to birth mode, infant diet, and antibiotic therapy.
