It is normal for infants to have 1~4 bowel movements in a day. The exact number of bowel movements is related to the infant’s age in months, feeding habits and other factors. The number of times an infant has a bowel movement in a day varies from person to person. Due to the immaturity of the infant’s digestive function and the weakness of the digestive function, the number of times an infant has a bowel movement in a day will generally be relatively high. If the infant is breastfed, the number of bowel movements in a day is usually 2 to 4. If the infant is artificially fed, such as formula milk or cow’s milk, the number of bowel movements in a day is usually 2 to 3. Infants will also have fewer bowel movements a day as they get older and with the addition of complementary foods to their diet, usually 1~2 times a day. The number of bowel movements a day can reflect the function of the gastrointestinal tract. If there is a sudden change in the nature of the stool and an increase in the number of bowel movements in a short period of time, accompanied by symptoms such as crying and restlessness, and thinning of the stools, then it is necessary to pay attention to this, and it is recommended that you go to the hospital in time, and under the direction of the doctor to carry out the treatment.
