1. Observe the baby's behavior and activity level: Healthy babies are usually active and have good appetite and sleep habits. If the baby shows abnormal symptoms such as fatigue, lethargy, loss of appetite or hyperactivity, it may need further examination.
2. Pay attention to the baby's weight gain: the baby's weight gain is one of the important indicators to evaluate its health status. Under normal circumstances, a baby should gradually gain weight within a few months after birth. If your baby's weight gain is slow or stagnant, you may need to consult a doctor.
3. Observe the baby's skin and hair: Healthy babies usually have smooth and elastic skin and thick hair. If your baby's skin is dry, red, itchy or other abnormal symptoms, or your hair becomes sparse or falls off, you may need to consult a doctor.
4. Pay attention to the baby's urine and urine: A normal baby should have multiple diapers and stool excretion every day. If the baby's urine volume is significantly reduced, the urine color is abnormal or the number of stools is significantly reduced, it may be necessary to consult a doctor.
5. Regular physical examination: It is very important to take your baby to a pediatrician for regular physical examination. Doctors can check the baby's growth and development by measuring height, weight, head circumference and other indicators, and carry out necessary laboratory tests. These are just some common ways to judge your baby's health. If you have any specific health problems or concerns, you'd better consult a professional doctor for personalized advice and treatment.
