Susan, My 3rd baby had this problem. Was an allergy to both citrus and dairy products. Her bottom would break open and bleed. The rash was so bad, that she could only tolerate cloth diapers. When the rash got really bad it would eventually progress into a yeast infection. The citrus seemed to cause worse problems than the dairy in our case. Why do moms have such a hard time giving up dairy products? Our culture is so brainwashed that dairy products are healthy and an important source of calcium. I really hate those "got milk" ads that are out right now. Especially the one with Melanie 'Griffith with her 3 kids, youngest one on her hip drinking a bottle full of the stuff. Turns my stomach. Anyone else? Lisa P. in Michigan
