Abdominal Circumference: 12.75″ (322mm)
Femur Bone Length (from waist to knee): 2.7″ (69mm) which is about the height of a US dollar bill

Each baby is about the size of a canary melon.

Catrina M. – “The twins are doing great, though I have some mild abdominal pains. I also have extremely increased appetite.”

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 during the 36th week 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 7 days.
