If Your Twins Were Born This Week
Your twins are considered to term. They are typically born as healthy as their singleton counterparts. Twins born during the 37th week average a hospital stay of about 6 days and normally go home with Mom when she leaves the hospital.
Most twin parents report no NICU time for their twins born this week:
Matt B.: No NICU. Born 37 weeks and weighing 6 lbs even, 5 lbs 13 ozs.
Amanda R. said that one of her twins (Born at 37+3) needed NICU for 3 nights. “That twin needed help with body temperature and sucking. While we were still in the hospital. We stayed for 4 nights so he (born at 4lbs 15 oz) spent one night in the room with us. The other twin, born at 6 lbs 12 oz, was with us every night. We went home after 4 nights and have been good since.”
James F.’s twins were born at 37 and 3 and went home on the third day.

What to Prepare This Week
When Mom is 37 weeks pregnant with twins, she is physically no longer able to do much preparation. Any leftover tasks you have will need to be done by Dad or someone else. Hopefully at this point you don’t have much left to do since your twins will arrive any day now.
By the time Mom reaches 37 weeks pregnant with twins, she is extremely uncomfortable day and night. She is ready for the twins to be born NOW.
