"How are the child's bowel movements and urination?" Tang Yiyuan took the pulse, examined the tongue coating, and pressed the child's stomach, then turned to the child's mother and grandmother and asked.
"Both are not very good. The urine is yellow, and the stools are dry. Moreover, he hasn't had a bowel movement for six or seven days now. It's really driving me crazy," the young woman said, her eyes reddening as she spoke.
"Don't worry, it's very normal for children to get sick," Tang Yiyuan reassured her, then followed up by asking, "Does the child usually drink breast milk or formula?"
"I don't produce much breast milk, so he's been on formula since he was three months old," the young woman replied.
"Hmm, have you changed his formula recently?" Tang Yiyuan nodded and asked again.
