If there is crying and spitting up, it is likely to be caused by an upset stomach, so you can touch your baby’s stomach. If the child has a painful expression, it is likely to have gastritis and other diseases. You can take oral medication to protect the gastric mucosa, such as Gaikoupian tablets. Drugs to aid digestion, such as polypeptide tablets and pepsin tablets, can also be used as appropriate. It is important to monitor your child’s overall symptoms during treatment, such as taking his or her temperature to see if he or she has a fever. If spitting up is severe, gastrointestinal stimulants can also be used to relieve the symptoms, such as domperidone suspension. Try not to let your child eat cold formula during treatment to avoid recurrence and worsening of the condition. If you are breastfeeding, the mother should also pay attention to improving her own diet and avoid eating raw and cold food to avoid affecting the nursing baby.
