Spitting up and overflowing are two common phenomena in the development of infants. Spitting up is a strong and forceful emptying of food from the stomach in larger amounts; overflowing is the involuntary backflow of the contents of the esophagus or stomach to the outside of the mouth, which may just be a burp that causes a small amount of milk to spill out from the corner of the mouth. Generally speaking, there is no big difference between mild vomiting and milk spillage, and no special treatment is needed. Sometimes when your little one has a cold or is sick, spitting up may be a little more serious than usual. However, as your baby grows older, this situation will improve significantly. If your baby has severe spitting up, sometimes with milk coming out of the nostrils, you should take your baby to the hospital as soon as possible. Why babies spit up Spitting up is related to the baby’s digestive tract, physiological characteristics and improper feeding methods. The tension of the esophageal muscles of infants and young children is low, which can easily cause dilation and slower peristalsis, so food is easily sloughed up. In addition, the stomach of infants does not hang down like older children and adults, but is in a horizontal position. The stomach has a small capacity and stores less food. Due to the presence of these factors, even under normal circumstances, when the baby eats too much and lies down immediately after eating milk, the milk will easily return to the mouth through the esophagus, causing spitting up. The reasons for improper feeding are: 1. Babies cry before feeding or are too eager to eat milk, so they can easily inhale air, and when the air overflows from the stomach, the milk is brought out and vomited; 2. Babies suck for too long (a normal nursing session is 10-15 minutes) or suck without milk, so that they suck too much air; 3. Newborns who are fed artificially have too large pacifier holes so that milk flows in too quickly, or the holes are too small and suck for too long, so that (The size of the teat hole should be such that the milk drips out slowly when the bottle is inverted, and the feeding time of each bottle should not exceed 10-15 minutes); 4. Formula milk is too hot or too cold; 5. Formula milk is diluted too much or the brand of milk powder is changed frequently; 6. Putting the newborn down after feeding or turning the newborn too much, etc. Incorrect weaning method is also a cause of vomiting Usually babies start to add complementary foods at 4 to 5 months, and it takes several months until they do not eat breast milk at all. During this time a new food should be given, from thin to thick, from light to thick, from less to more, so that the baby gradually adapt. Otherwise, the baby will also vomit due to force feeding or not easy to accept the new food. Ways to improve baby vomiting 1. burp After the baby drinks milk, as the lower part of the stomach is milk and the upper part is air, it will cause pressure in the stomach and overflow and vomiting. Therefore, you should help your baby to burp in time to let the gas out. As soon as the pressure in the stomach is reduced, the spitting up and overflowing of milk can be reduced naturally. 2.Position therapy If burping is difficult, then pick up your baby upright and let him lie on your shoulder for at least 30 minutes, then put the pillow up high and let your baby lie down on his right side, which can effectively increase the speed of stomach emptying. 3.Diet therapy Increase the number of feedings, reduce the amount of milk each time, and do small amounts of multiple meals. Hold your baby appropriately for a while longer after feeding, and don’t rush to put him flat on the crib, which will help reduce reflux. However, milk that is too thick may cause gastrointestinal obstruction or diarrhea. 4.Medication If spitting up or overflowing milk is serious, ask your doctor to prescribe some medication to stimulate bowel movement. However, medication is the last thing to be considered.
