Hello and thank you for the question given

We understand that you want to know if your son’s bright yellow and runny stool is normal and a way to change the consistency of his stool, am I right? Correct me if I’m wrong about your concerns.

For your information, bright yellow and runny poop can occur in formula-fed toddlers but in a case where it becomes more frequent than usual and extremely runny, it could be diarrhea. Some of the common cause of diarrhea in children are:

• Infection such as viral gastroenteritis
• Food poisoning

Some other serious causes of diarrhea that needs immediate attention are:

• Irritable bowel disease
• Ulcerative colitis
• Crohn’s disease
• Food allergies
• Celiac disease

Because of the fact, your son has had a fever and diarrhea we strongly suggest for you to talk to our doctor via teleconsultation to know more about your son’s condition.

I hope this explanation helps you in any way possible. Thank you
