The baby vomits when he eats milk, he vomits after drinking, he vomits after burping and sleeping, is the baby sick? New parents may be very confused, worried that the baby will not be able to keep up with nutrition, but in fact this is a normal phenomenon! Spillage and vomiting is one of the most common physiological phenomena in babies, and is common in babies between 4 and 6 months of age. Most babies will gradually get better around 6 months of age, but a few may continue to improve until around toddlerhood. After a baby has finished feeding, milk flows out of the corners of the baby’s mouth, or spurts out with hiccups, or if the baby is very excited and moves a lot, a lot of milk may jet out of the mouth or nose at once. Spitting up is often frightening, but if it only happens occasionally and the baby is growing well, is in good spirits, eats well, and shows no pain or discomfort when spilling or spitting up, parents need not worry about it. It is normal for milk to come out of the nose (milk lumps) because the nose and mouth are originally connected. Overflow and vomiting are related to the anatomical characteristics of the baby’s digestive organs. The newborn baby’s digestive system is not yet developed, the stomach is small and horizontal, and the gastric outlet (lower mouth) pyloric sphincter is tight and the entrance (upper mouth) pancreatic sphincter is loose, so the contents of the esophagus or stomach can easily flow backwards to the outside of the mouth, especially when the baby eats too fast, eats too much, swallows a lot of air or eats milk with excitement. Spitting up can also be a symptom of some diseases. If your baby is spitting up while not in good spirits, not eating milk, accompanied by various uncomfortable manifestations such as bloating, diarrhea and crying, you should consider seeking medical attention as soon as possible. Neonatal peritonitis, intestinal obstruction, intussusception, pneumonia, esophageal atresia, intestinal atresia, etc. can be manifested as spitting up. If severe overflow and vomiting can try this: a. Master the time of feeding The emptying time of milk is about 2-4 hours, too frequent feeding, the previous milk in the stomach has not been digested, it will affect the next milk consumption, and the expansion of stomach capacity will lead to overflow and vomiting aggravated. 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. Breastfed babies are usually less likely to swallow air if they have the correct posture (so it’s normal to not burp after breastfeeding, there’s no need to burp all the time); bottle-fed babies can pause to burp a few times during the breastfeeding process. Fourth, right-side lying position to prevent accidental sucking Spitting up milk is not terrible, but accidental inhalation of milk into the respiratory tract can lead to suffocation. Padding the upper half of the body (head-high, foot-high incline) and lying on the right side can prevent spitting up and aspiration. In addition, breastfeeding should be done in a quiet and relaxing environment, avoiding noise, bright light and other stimuli; bottle-feeding babies should choose the right size pacifier hole; too large a pacifier hole is too fast and easy to choke on milk, too small a pacifier hole is too hard to suck milk and easy to swallow too much air; do not tease your baby immediately after feeding.
