Twice!! I had one girl who was constantly having diarrhea. Mom was concerned as well. She went to the doctor and they did tests etc and nothing. Doc said she was fine. Mom said she was cutting out milk and immediately it was better. We have continued feeding her dairy products but for some reason when she drinks cow's milk it causes diarrhea. I am so glad mom was on board with it and we worked together.

2nd child - I had a new girl start in Sept last year. She always had runny diarrhea type poops and two or three a day. It was so annoying!! When we had any sort of virus running through daycare it was worse. I mentioned to mom about possibly trying to cut out her milk/dairy and see if it changed things. She was not on board with it. She also told me that it never happened at home for her. There is no way it was ok to poop like that IMO. I began to call mom after the 3rd diarrhea every time for pickup. How did I know the child wasn't sick? There were times I didn't send her home and it ended up being something and passing it on to the other kids. One day I counted 9 poopy diarrhea diapers I had to change (3 kids)!! This child left my care in Feb. I still wonder if this was the reason they left. All I know is I love not having to change constant yucky diapers.
