27 Weeks Pregnant with Twins

Here’s what to expect when you are 27 weeks pregnant with twins:

Fetal Development

By 27 weeks in the twin pregnancy each of your twins averages about 14.5″ long from head to foot with the following measurements:

Head circumference: 10.5″ (267 mm)
Abdominal Circumference: 9.3″ (236 mm)
Femur Bone Length (about from the waist to knee): 2″ (51 mm)

What to Expect

Typical weight gain for Mom at this point is between 1.25 to 2.0 pounds/week (0.6 to 0.9kg).

If Your Twins Were Born This Week

Your twins are very early preterm and the odds of survival are better than weeks past. However, twins born during the 27th week still risk major medical complications and life-long health issues.

What to Prepare This Week

When Mom is 27 weeks pregnant with twins, discuss how you will be feeding the twins. If Mom will be breast feeding, look at twin feeding pillow options to help support the babies while they eat.

Dad’s Thoughts

By the time Mom reaches 27 weeks pregnant with twins, you should be well on your way to preparing any other children for their arrival. This includes making your own plans for how you’ll juggle the twins and a toddler (or other children).

Still wondering how to prepare for your twins? I cover specific things you should know and prepare for in my Dad’s Guide to Twins book. Learn more about the book here.
