Want to cry

I feel so bad for Emilie, it all started January 21st. The kids were really good, so we went to McDonalds to get them some ice cream. Less than 2 hours later, she had a diarrhea accident. It has not stopped since then. We took her last week to the DR office and they could not find anything wrong with her. There is no other symptom at all. No fever, no loss of weight, not dehyrdrated, no tummy aches, not lethargic, just the diarreaha. They told me to keep an eye on her and let them know if gets worse, it did not, so we did nothing except change her diet a bit. Last night she went to the bathroom and everything was normal. This morning she woke up and it was back to the runny poop. UGH It looks like I will have to keep a journal of everything that she eats from now on until we figure out what is going on. I feel so very overwhelmed that I just do not know what to do.
