Umbilical hernia is a type of hernia with a high incidence in the neonatal period, but it also has a high self-healing rate. For a mild umbilical hernia, if the child is under two years old, it is recommended to wrap a coin of one dollar or fifty cents in gauze and press the coin against the umbilicus. In addition, the umbilical cord is wrapped around the umbilicus so that it is pressed against the umbilicus, and slowly the child’s intestinal canal stops protruding and the umbilical hernia grows up. If the child is less cooperative, and if the hernia does not protrude when he is sleeping, he can lie down without the umbilical cord. If the child is active, the umbilical cord can be wrapped around the child and a coin can be used to put pressure on it.
