<s>[INST] My son is almost 3 yrs old and just passesd some greenish clay looking stools. There was also a red line looking thing. He has been drinking this v8 drink mixed with fruit punch gatorade, so I can t tell if it s that, or blood. I m freaking out and very worried. I don t know if I should take him to the ER? [/INST] Hi... Thank you for consulting in Chat Doctor. It seems your kid is having viral diarrhea. Once it starts it will take 5-7 days to completely get better. Unless the kids having low urine output or very dull or excessively sleepy or blood in motion or green bilious vomiting...you need not worry. There is no need to use antibiotics unless there is blood in the motion. Antibiotics might worsen if unnecessarily used causing antibiotic associated diarrhea. I suggest you use zinc supplements (Z&D Chat Doctor.  </s>
