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.
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.
