Do twins born at 36 weeks need NICU?

As a result of complications, late preterm babies may need to be admitted to a neonatal intensive care unit (NICU) or even readmitted to the hospital after discharge. RDS is by far the biggest risk for babies born at 36 weeks. Baby boys seem to have more trouble than late preterm girls.
