My 2.5 year old has been having diarrhea on and off for over a month. It’ll start and get extremely watery and last for about a week and then get a bit better but then ends up coming back. He caught a stomach virus over Thanksgiving. He threw up for a couple hours and then the diarrhea started and he hasn’t been back to himself yet. Took him to the pediatrician when the diarrhea came back the second time and he said it was probably a different virus & his stomach was still trying to heal. But here we are again on the third round of it. Any suggestions? Should I look into a more serious cause? Concerned momma. Thank you ladies!
