I. Master the time of breastfeeding The emptying time of breast milk is about 2-4 hours, too frequent breastfeeding, the previous milk in the stomach has not been digested, which will affect the next milk intake, and the expansion of stomach capacity will lead to overflow and vomiting of milk. In addition, don’t wait until your baby is overly hungry to feed, as it is easy to over-eat and spit up. Adjust the breastfeeding position. You can try to let your baby breastfeed in a semi-recumbent position or hold your baby vertically, so that your baby’s body has a certain inclination and milk can easily enter the small intestine through the exit of the stomach. After breastfeeding, you can let your baby lie on your mother’s shoulder, and your mother can gently pat your baby’s back with her hollow palm to help your baby get rid of the air swallowed during breastfeeding. For breast-fed babies, it is usually not easy to swallow the air if the breast-feeding posture is correct (so it is normal to not burp after breast-feeding, there is no need to burp all the time); for bottle-fed babies, you can pause a few times during the feeding process and continue to breast-feed after burping. 4. Right-side lying to prevent accidental aspiration Spitting up milk is not terrible, but accidental aspiration into the respiratory tract can lead to suffocation. Padding the upper half of the body (head high on the slope of the feet) and lying on the right side can prevent spitting up and aspiration.
