Tannis, I am wondering the exact same thing! My DD started having conspitation about a month and a half ago. Then, all of a sudden last Sunday it went to severe diarrhea. We took her to the doctor the next day, and he said it was a stomach bug and it would go away on it's own. I mentioned to him that she also seems to have redness and dry skin behind both her knees. He said it was eczema, and to use a lotion on her. So fast forward to Thursday, diarrhea still bad and the eczema spreading. Took her back to the doctor, and this time we saw a different doc. She said that the stomach bug may have triggered a milk allergy, and to be on the safe side to try her on soy formula till the diarrhea went away. The first night, she had her first solid (well pasty) poop. Then next day was better, and today she's only pooped once and it looked normal. So, I think the soy milk is helping. But, now she seems to be reacting to the lotion we are using on her legs, or maybe it is something else. She also has bumps that started on her legs, and have spread to her arms and neck area. They are not red, just bumps. So, off we go tomorrow to the dermatologist. Luckily, I used to work for him so he's going to fit us in and hopefully give us an idea if this is an allergy, or skin condition. I will post and let you know how that goes FYI. But I would switch to a soy formula if I were you and see how that goes. Or before doing that, go to a dermatologist for their opinion.
