It sounds like it started out as allergic colitis (the bloody stool) which most babies outgrow by 1 year of age, and now he seems to have more of an "intolerance" than an allergy. just my impression, as a mom of another baby with milk-induced (among other things) allergic colitis. As he just turned 1, we are planning to test his reactions to his former colitis-producing foods soon. --Robyn
