My 10 month old baby has blood stained stool. She passes very hard stool every time and cries many times before passing stool. She is cranky most of the time. We have consulted many pediatricians and tried losts of medicines, but no effect. only thing that milded the symptoms was gripe water. but yesterday there was little blood in stool. She doesn't eat much solids and is formula fed. We even tried switching formula.
