If Your Twins Were Born This Week
Your twins are late preterm and the odds of survival are very good. They are in good company as many twins are born during this period. Twins born at 33 weeks have an increased risk of permanent health issues but generally speaking are healthy. Twins born this week average a hospital stay (including the NICU) of about 20 days.
