Diarrhea

When should I take my son to the doctors for diarrhea. He had his first actual diarrhea poop Friday night. That day he had two other poops that were not necessarily diarrhea but not solid which is also normal for him cuz normally his poops are mixture of solid but also kind of mushy. But his first actual diary of poop was Friday night. He had diarrhea all day yesterday on and off I think in total of like five diarrhea poops possibly six. We woke up this morning and he had his first diarrhea of poop already. He's been eating just fine and acting just normal doesn't seem to be uncomfortable I've been trying to push fluids and giving him electrolyte water. No fever or any other symptoms it's just a diarrhea He's only ever had diarrhea like this one other time and it lasts a day and that was it. Just need some advice cuz I'm not sure if I am wearing too much or if this is something I just got to kind of wait it out as long as no other symptoms are showing
