<s>[INST] Hi, My daughter has been a little unwell overnight, she complained of her stomach hurting, then an hour later she vomited a little, then just after has been having regular very loose BM. I thought maybe a stomach bug, but she has been fairly happy throughout it and we put her in the bath as she had messed her self and then has done another BM in the water and washing out the dirty water, there seems like a little sand left behind. She is 6 [/INST] Hello. I just read through your question.I agree with your initial diagnosis, that this is a stomach virus. Stomach viruses come in many varieties. The symptoms you describe sound like a mild form. As long as she maintains her hydration, she will be fine. The illness will resolve on its own within several days. </s>
