As long as the protrusion of the baby's belly button does not exceed 5cm, you can gently press it back by hand.

However, if you can't press it back by hand, you need to see a doctor to avoid intestinal ischemia caused by abdominal wall compression.

The baby's navel bulge is a disease from the doctor's point of view, which is called umbilical hernia. Most babies of this disease can heal themselves. As the baby grows up, the abdominal muscles become stronger and stronger, and 8% of the babies can heal themselves before the age of one.

There are some serious babies who can heal themselves after they are two years old. However, if the baby is over two years old and still hasn't recovered, Bao Ma can't be careless and needs to take the baby to the hospital for active treatment.

In order to avoid umbilical hernia, the baby's stool should be unobstructed at ordinary times. Because in the case of constipation, abdominal pressure will increase, and umbilical hernia will easily occur. It is also an important way to prevent the baby from crying violently.
