My daughter is 19 months old. From around 8 months , they started having problem of hard stool, sometimes there used be bolld with her stool. But with increased water intake and fruit juice and vegetable intake , the problem subsided. Now again I can find strains of blood in her stool , though there is no constipation.Her rectum stretches and the blood comes out. She doesn't cry or anything. I am a little worried. What should I do?
