Question 1: My son is four and a half years old. He urinates normally during the day and knows how to say \”I need to pee\”. However, it has been two months since I woke him up at night and he still doesn\’t know how to get up and pee on his own. Will wet the bed. Many children of the same age know how to wake up at night, why can\’t he learn? Is there any other reason or disease? Dr. Cui Lixia answered: Generally you should not wet the bed at this age. It is recommended to see a urologist to see if there are any problems with the development of the urinary system. In addition, do an MRI to check whether there is spina bifida occulta. If everything is normal, you need to see a neurologist. In addition, be careful not to eat liquid food, porridge, water, or fruit at night. Porridge and water can be drank during the day, which will not affect the child. Problem: A two-year-old baby has had mumps for a week. His cheeks are a bit swollen but there are no ulcers. I just went to the hospital yesterday and the doctor asked me to apply Jinhuang Powder externally. I would like to ask what is the best way to mix Jinhuang Powder for external application? Dr. Luo Zhen’s answer: Adding some isatis root and indigo naturalis powder can help reduce inflammation. Be careful to mix it with medical Vaseline. It usually takes about 7 to 10 days to recover, and more dynamic observation is needed. If the child has ulcers, he needs to be treated by a surgeon in time. Question 3: The baby is six and a half months old and has had diarrhea for three days. The stool is porridge-like, yellow in color, accompanied by white granules, and has a sour smell. Yesterday, I had diarrhea six times a day. I fed the baby montmorillonite powder and probiotics, and the condition improved slightly. My baby won’t take montmorillonite powder and it’s difficult to feed him medicine. What should I do now? Dr. Zhang Yanmei’s answer: You can replace it with tannic acid protein yeast powder, 1 packet each time, 3 times a day, before meals. Take Baoer\’an Granules after meals, 1/4 packet each time, 3 times a day.
