How do parents judge whether their children are healthy or not?

I can tell you some methods that parents can use to judge whether their children are healthy or not. However, please note that my answer is for reference only. If you have any specific health problems or concerns, I suggest you consult a professional doctor for accurate diagnosis and advice.

1. Observe children's daily behavior: pay attention to whether children have normal sleeping, eating and activity habits. If the child shows abnormal behavior, such as persistent fatigue, loss of appetite or hyperactivity, further examination may be needed.

2. Pay attention to the child's weight and height: measure the child's height and weight regularly and compare it with the standards of children of the same age. If your child's growth curve deviates significantly from the normal range, you may need to consult a doctor.

3. Observe the child's skin and hair: Check whether the child's skin is abnormal, such as eczema, herpes or other rashes. Observe whether the child's hair is falling off, thinning or other abnormal conditions.

4. Pay attention to children's emotions and behaviors: observe whether children's emotions are stable, whether they have anxiety, depression or other emotional problems. Pay attention to whether the child's behavior is normal, such as concentration and social skills.

5. Regular physical examination: Take your child for regular physical examination, including measuring basic indicators such as body temperature, blood pressure and heart rate. In addition, depending on the child's age and sex, the doctor may recommend specific screening or examination, such as eyesight, hearing and blood test. These methods are only a preliminary reference for judging children's health. If you have any questions or concerns, it is best to consult a professional doctor for detailed evaluation and diagnosis.
