My 2-year-old daughter in diapers has been having terrible constipation for about three months. It didn't respond to the usual dietary approaches or mineral oil, so our pediatrician asked us to try 1/2 capful of Miralax (laxative) to help her stop holding it in. That helped loosen things, but what resulted was about 8 small wet stools per day (exhausting to change) with no large stools ever coming. So the doctor said increase Miralax to 1 capful, but that just caused about 15 small stools per day. So now we reduced the Miralax and added Benefiber, but still, it's all small stools 5-6 times a day, and never one big stool. She pushes so hard, and hardly anything comes out. On top of this, she has been on a low-grade antibiotic for kidney reflux for over 1 year, so I don't know if that is doing something to the digestive process. Has anyone experienced something similar? If so, what resolved it? Does this sound just like usual stubborn 2-year-old constipation, or do you think it sounds like a bigger problem?
