My daughter had constipation problems. We tried everything the doctors told us to. With no positive results. Several months and several biopsies later they recommended surgical modification. I revolted at that idea. We refused to follow this path. My daughter was found later to have dairy allergies. At this time the leche insisted my daughter could not be allergic to breast milk. We switched to soy. Still pooping was painful and impossible. Around this time a complete stranger told me her daughter suffered this way until she put barley cereal into her bottle. Truth be told she started pooping freely. Once the concrete was passed. By this time we had to manually stimulate her movements bc her sphincters were not working properly. To this day we remember how horrible this episode was and thank the good fortune of the barley cereal.
