Methods: Mommy first rubs it with the palm of her hand, and then slowly massages her abdomen clockwise for about 30 times, which can help the baby to promote intestinal peristalsis.

Let the baby lie in bed. Parents can tell stories or sing songs to their babies so that they can fully relax. At the same time, put the four fingers of the right hand together and gently massage clockwise around the baby's navel, preferably every time 15-20 minutes, once a night.
