Hi All, As a personal anecdote...PJ has greenish sour smelling stools when I drink a lot of OJ or citrus juices. Totally benign, thank goodness. I think that is also what is causing his spitting up now. I have totally eliminated (no easy task as many of you know) all traces of dairy from my diet, and he is still spitting. After eliminating the citrus for 3 days, his spitting has reduced by 1/2. We'll see! Jay Jay Simpson, CLE Sacramento, CA Mama Milk is the Greatest!
