Thanks for writing in.
I understand that the frequency of passing stools has come down from the earlier episodes of watery motion , but now your daughter is passing blood and mucus in the stools.
I would advise you to follow good hygiene to prevent re-infection. Always wash your hands with soap and water after using the bathroom, after a nappy change, and before preparing food.
Give your daughter Pedialyte
(oral rehydration solution) to correct dehydration
Keep the anal region clean and dry.After the baby has a bowel movement , clean the area gently with water and then pat dry. Avoid using wet wipes or harsh soaps.
If a wound is present at the anal region, you might want to take her to the paediatrician for assessment.
Sometimes, it is quite possible that the repeated watery motions might have caused an excoriation of the anal region.
Hope this helps.
