1. Weight gain: The baby's weight gain is one of the important indicators to evaluate its health status. In the first few months after birth, babies should gain proper weight every week. You can refer to the baby's growth curve to find out whether the baby's weight is growing normally.
2. Sleep: A baby's sleep is very important for his health. A normal baby should have regular sleep time to maintain a good sleep quality. If the baby often wakes up, has difficulty falling asleep, or sleeps for too long or too short, it may be necessary to further observe and consult a doctor.
3. Diet: The baby's diet is very important for its healthy development. Under normal circumstances, the baby should have a good appetite and be able to eat normally. If your baby refuses to eat, eating too much or too little, you may need to consult a doctor to find out why.
4. Defecation: The baby's defecation is one of the important indicators to evaluate the health of his digestive system. Normal baby defecation should be regular, and the color and texture of feces should be normal. If your baby has constipation, diarrhea or abnormal stool, you may need to consult a doctor to understand the reasons.
5. Mobility: The baby's mobility and development milestones are also one of the important indicators to evaluate his health. A normal baby should have enough mobility, such as looking up, turning over and sitting up straight. If the baby's activity ability is obviously lagging behind or has other abnormal performances, it may be necessary to consult a doctor to understand the reasons.
Please note that the above are just some commonly used indicators and methods, and the health status of each baby may be different. If you have any questions or concerns about your baby's health, it is recommended to consult a professional pediatrician for detailed evaluation and guidance.
