Question: how is a 3 month old baby poop supposed to look like?
Answer: Expect your breastfed infant's stool to be soft to runny in texture. It may also be watery, almost like the consistency of diarrhea. The texture may resemble mustard and contain small, white seed-like particles. Each bowel movement should be about the size of a United States quarter (2.5 centimeters or larger.)
