Final answer:
The initial treatment for a baby with the umbilical cord wrapped around its neck should involve gently loosening the cord to avoid any obstruction or strangulation.
Step-by-step explanation:
Upon delivery of a baby's head, if the umbilical cord is wrapped around its neck, the initial treatment should include loosening the umbilical cord gently. It is important to carefully unwrap the cord from around the baby's neck to ensure that it does not cause any obstruction or strangulation. Once the cord is loosened, the baby can continue with the delivery process and the cord can be cut after the baby is fully born.
