The peritoneal muscles in the abdomen of newborns are not yet fully developed, so the abdomen will sag and look like the baby’s stomach bulges like flatulence, but most of them are normal. Secondly, consider improper feeding of the baby, the baby is too eager to eat milk and incorrect posture, which leads to the baby sucking in a lot of air in the stomach and finally causes the baby to be bloated. In addition, the mother consumes a lot of gas-producing food and feeds it to the baby through breastfeeding, which is also the cause of intestinal flatulence in babies. For the above reasons, the following relief methods are used: (1) Avoid the baby crying for a long time. When babies cry, they tend to inhale a lot of air and accumulate too much gas in the abdomen causing bloating. (2) After feeding, hold the baby upright with the head resting on the mother’s shoulder, and pat the mother’s hand in a hollow shape on the baby’s back from bottom to top until the baby burps, so that the gas in the stomach is discharged from the esophagus. (3) Use a pacifier suitable for the baby’s age to avoid inhaling a lot of air while breastfeeding; breastfed babies must pay attention to the correct feeding posture and try to let the baby’s mouth hold the mother’s areola to reduce the possibility of swallowing air. (4) Keep your baby’s abdomen warm. The mother can rub her hands together and place them on the baby’s abdomen, or use a hot towel to warm up the baby’s abdomen. In the fall and winter, pay attention to keeping the baby warm, especially at the belly button, the abdomen is warm, reducing the occurrence of intestinal cramps, increasing intestinal peristalsis, promoting the baby’s exhaustion and defecation, and reducing abdominal distension. (5) Give your baby more abdominal massage. Massage should be clockwise, in the direction of intestinal peristalsis, massage 10 minutes a day. Or use wind repellent oil on the abdomen, which helps intestinal peristalsis and gas discharge. (6) Baby mothers try to reduce the intake of gas-producing foods, such as soy products, etc. (7) Put a mask on the baby or use a scarf to protect the baby’s mouth and nose when going out to reduce the inhalation of cold air. In short, if the newborn baby eats milk normally, exhaustion and defecation are normal, weight gain is also normal, abdominal bulge is normal like belly distension. If the newborn does not have normal bowel movements and exhaustion, eats little milk or does not eat, even with vomiting, the most common causes are meconium intestinal obstruction, neonatal sepsis, congenital megacolon, neonatal hypoxic-ischemic encephalopathy or intestinal torsion, etc. A thorough examination is needed to make a clear diagnosis for early treatment.
