about 2 months ago my 2 year old had c-diff. since than he has been retested and the test came back negitive. His stools are still not normal, they are loose to watery. The doctors tested him for parasites and a bunch of other things and it was all normal. The doctors say it will run it's corse and will take awhile to build up good bacteria again. I give him yogart everyday and it still is only a little better, could the doctors be missing something, should I get a 3rd or 4th oppion or see a specialist? very concerned mother
