The number of stools for a four-month-old baby is about 0-4 times. The number of times a baby poops depends on the feeding habits of the baby. If the baby is breastfed, because breast milk is better digested and absorbed, it is normal for the number of stools to be around 2-4 times. If the baby is more than 4 times, we should consider whether the baby is diarrhea, this situation mother should improve the diet in time, do not eat too much raw and cold stimulating food, to avoid passing through the breast milk to the baby. If it is a mixed feeding, once a day is normal; if it is a pure formula-fed baby, there is no fixed value for this, 0-4 times are normal. There is also a situation where the baby will have a saved belly, not relieving a stool for several days, if the baby eats milk well and is in good spirits, there is no need to pay special attention to this, it is a normal phenomenon.
