Question

My baby is two months old and has been having diarrhea for 7 days. The color of the stool was light blue with a sour smell a few days ago. I changed the brand of formula milk, and now the stool color has turned yellow, but there are still bubbles and grains, and it still has a sour smell. Could this be due to the formula being too concentrated?

Answer

The color of a newborn’s stool can vary depending on the formula they are drinking, which is normal. Here are some things to note about stool color:

  1. The lighter the color, the more likely it is an abnormal discharge of bile.
  2. Black stools may indicate bleeding in the upper gastrointestinal tract.
  3. Red stools could be a sign of bleeding in the lower gastrointestinal tract. You mentioned that your baby’s stool contains bubbles and grains, which might be due to some ingredients in the formula not being fully absorbed or because the baby’s digestive system has not fully developed. If the stool color has turned yellow and only occasional bubbles and grains are present, there is usually no need to worry too much. However, if this condition persists or is accompanied by other symptoms, it is advisable to consult a pediatrician for professional advice.
