[|Human|] hello. our 3 month old daughter has been getting a small amount of blood in her diaper. we took her to the ER a couple of weeks ago and she was admitted because she was also having vacant stares. they did a CT scan on her head which was normal, a 20 minute EEG which was normal and two lumbar punctures which were unfortunately unsuccessful but they tested it anyway and it was fine. They ended up diagnosing her with the rotavirus. she is still get periodic blood in her diaper though and wondered what might be other causes. she has been straining a bit the last few days but as she s breastfeeding isn t constipated. can you offer any advice please?
[|AI|]  Dear parent, I understand your concerns, but the color of blood should give a clue on the site of bleeding.  If bright red blood then the cause is in rectum if dark brown then the cause is in the intestines.  The most common cause is a tiny crack of the anus due to straining and passing hard stools. This is treated by avoiding constipation. Another common causes include 1) milk allergy 2) swallowing blood from cracked mothers' nipple 3) lactose intolerance 4) infection
