Hi doctor! My baby is only 3 months old, I give him formula milk and breast milk. I have the following questions that I hope you can help me with. Baby has a bowel movement once a week, and usually he has yellow stools

Stool is the final part of the digestive process, consisting of waste products that are eliminated from the body such as undigested particles, bacteria, salts, and other substances. Stool can sometimes vary in color, texture, amount, and odor. So what is normal stool?
