My 14 month old DD breastfeeds frequently still, but does eat some solids. I just recently introduced whole cow's milk to her on the pediatrician's recommendation. She just had a poopy with blood in it. She's had about 1 or 2 oz of cow's milk per day this week and that's all that has changed in her diet (except the other odd things that find their way to a toddler's mouth). She doesn't seem to be bothered otherwise...no eczema, no diarrhea or other rashes. Could she be sensitive to the cow's milk? Should I drop it from her diet?
