Re: breastfeeding colitis. It usually is identified within the first 2 weeks of the baby's breastfeeding experience. I do not know of cases where it took 3 months to develop, tho this might be possible if baby was on non-milk fluid for 3 months and then went to breast. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% %% Kathleen G.
