It is normal for breastfed babies, especially those under five to six weeks of age, to be stooling quite frequently. Some babies have a bowel movement following each feed. A baby under six weeks should be stooling at least two to three times a day. At this time he should be having regular, substantial bowel movements. An exclusively breastfed baby's stools should be soft and unformed.
Young babies have an immature digestive system.
It is also not unusual for them to strain when they have a bowel movement. An exclusively breastfed baby's stools should be soft and unformed. Spitting up following a feed is also very common. Usually spitting up ends by around six months of age, as your baby is becoming more upright. You should not rely on this information as a substitute for personal medical attention, diagnosis or hands-on treatment.
