In principle, diapers should be changed as long as they are wet or dirty. Generally speaking, diapers should be changed within 4 hours, and must be changed when there is stool. However, it is impossible for everyone to observe the baby in real time, and there may be omissions. It is recommended that you focus on the following time points to improve efficiency:

1. 10-20 minutes after each feeding or feeding;

2. After each bowel movement;

3. Before falling asleep;

4. When you wake up.

5. When taking your baby out, don't forget to change diapers frequently.
