Depending on the amount of meals a baby has in a day and the structure of his/her diet, the number of times a 19-month-old baby has a bowel movement is not fixed. Generally speaking, once a day or once every two days is within the normal range. Whether a 19-month-old baby’s stools are normal or not is not only related to the number of stools, but also the nature of stools. As long as the baby’s stools are regular, soft, without mucus, pus and blood, without diarrhea and other symptoms, stools once a day or once every two days, or even two or three times a day, are generally normal. It is worth noting that the baby’s digestive function is generally immature, more prone to constipation, diarrhea and so on, so it is recommended that the baby to develop the habit of regular defecation, and gently massage the baby’s abdomen every day, to promote intestinal peristalsis, to help its digestion. In addition, if the baby has a change in bowel habit or a change in the nature of the stool, should go to the hospital, under the guidance of the doctor for treatment.
