How to handle vomiting in a 2-year-old baby?

Patient's question:

Age Description: Yesterday morning, the baby had a normal bowel movement. At 10 a.m., the baby ate breakfast (noodles + egg yolk). After finishing breakfast, the baby pointed to the lower abdomen and said they had a stomachache, and had a slight sweat on their head. After that, the baby was always held. By noon at 12 p.m., the baby couldn't hold it in anymore and vomited all of the breakfast. After vomiting, the baby's condition immediately improved. The baby didn't eat anything in the afternoon, only had two biscuits. In the afternoon, the baby had one bowel movement (it was relatively loose but not watery). From 4 p.m. to 6 p.m., the baby slept. For dinner, the baby drank a small amount of rice and yam porridge and ate one dumpling. At 8 p.m., I gave the baby some Huoxiang Zhengqi liquid. By night, the baby slept

Hello! It is likely due to a stomach or intestinal cold, and you should consider taking Mamiyao and Lueshengsheng, etc.
