DBF, direct breast feeding (ie, breastfed at the breast); EBM, exclusively breastmilk fed.
a
Fisher exact test P value.
b
EBM feeding at 12 wk was defined as 24-h recall of no liquid other than breastmilk, EBM through 12 wk estimated by participant recall of introduction of other liquids or solids at any time in their infant’s lifetime.
