"Any patient born less than 35 weeks gestation should stay in a neonatal intensive care unit until baby can maintain its own temperature, does not require oxygen assistance, can eat by mouth, and is gaining weight," said Tara Lyngaas, a nurse manager in the NICU department of Baylor Scott & White McLane Children's Medical Center, in an email to Fox News Digital.

"Most babies are discharged close to the mother’s original due date," Lyngaas continued. "Depending on the baby’s condition, a baby’s stay in NICU can be reduced or added."

Lyngaas noted that parents of premature babies have been able to help their newborns develop by participating in baby care times, providing "kangaroo care" (skin-to-skin holding), singing, reading and praying at their bedside.
