Step-by-step explanation:
The practice of applying alcohol to promote drying of the umbilical cord has fallen out of favor in recent years. Previously, it was believed that alcohol could help prevent infections.

Today, it is recommended to leave the umbilical cord untouched and allow it to dry and detach on its own.
