My two month old infant is on a mixture of breast milk and an occasional bottle or two of Similac Soy Formula and I was wondering what type of stool is normal for such a diet? There are times that it really varies from watery to soft as well as the color varying from mustard to dark brown. I have eliminated dairy practically a hundred percent from my diet, which has helped immensely with her gas and tummy aches approximately six weeks ago. I still think that my breast milk is causing her stools to be watery. What are everyone else's experiences with their diaper changes?
