Hi there I found this list of foods that can turn stool red for toddlers: Red Jell-O, red or grape Kool-Aid Red candy, red licorice Red cereals Red frosting Red food coloring Beets Cranberries Fire Cheetos Paprika Red peppers Rhubarb Tomato juice or soup, tomato skin If your 3yr old are any of these or had medication that lists stool discoloration in the side effects I wouldnt be too worried and just see if it goes away next time. If not it might be blood and that would be a reason to talk to your doctor .
If it happens again then bring your lo to the pd
Maybe is because of the food intake.
See pd
