Overfeeding can exist when breastfeeding if factors such as feeding too often occur. Overfeeding refers to an imbalance between the baby’s nutritional needs and supply, giving the baby too much nutritional supply. If breastfeeding is more frequent, the feeding time is too long, and the baby is always fed even when the baby is not hungry, the baby is prone to obesity, indigestion, and spitting up, which is considered overfeeding. Postpartum women are advised to actively learn about feeding their babies, generally on-demand breastfeeding, and to be good at observing their babies’ behavior when they are breastfeeding. Don’t let your baby be hungry or overfed to prevent adverse effects on your baby’s health. If there is overfeeding of the baby, it is recommended to consult a doctor in time and give appropriate treatment under the doctor’s guidance.
