Newborns may experience spitting up as their milk intake increases, which is due to their relatively small stomach capacity and relaxed stomach muscles. This usually lasts for a few months. If the baby has symptoms like abdominal pain or vomiting, it may be related to indigestion. It is recommended to give the baby a detailed examination, check for abdominal pain, and if confirmed, perform clockwise massage on the baby’s abdomen, and administer probiotics. Remember to burp the baby after feeding and hold them gently for a while, allowing the baby to assume a low body lying position.
