DD is 6 months old and has been having diariah for 5 days now. It is green and really watery. She is pooing every 1-3 hours and only peeing maybe 3 times a day total. She doesn't have any other symptoms and seems to be eating just fine. Previous to this she only went poo once a day at most but normally every 2 days. When should I worry? How do I get it to go away? Her pedi said to call on the 5th day if she still had diariah or if she hadn't peed in 12 hours.
