Whether the stools of 3-month-old babies are normal or not, you can observe the number of times your baby’s stools are passed and the nature of the stools. If a 3-month-old baby is exclusively breastfed, the stools are usually yellow or golden yellow in color, mostly in the form of a uniform paste or with a few yellow fecal pellets, or thinner, with a sour odor. The average number of bowel movements is 1-3 times a day, usually decreasing after the addition of complementary foods. If artificially fed, stools are usually dark yellow, formed and hard. They occur about 2-4 times a day. If the number of times is obviously abnormal, it means that the stool is not normal. In addition, you need to pay attention to the nature of your baby’s stools, for example, whether the baby’s stools are thin, whether there is mucus, whether there is pus, or whether there is blood in the stools, and so on. If there is any abnormality, it is recommended to consult a doctor in time, under the guidance of the doctor, complete the relevant examination, clarify the cause of the disease, and follow the doctor’s instructions to be targeted treatment.
