Here’s what to expect when you are 17 weeks pregnant with twins:
By 17 weeks in the twin pregnancy each of your twins is about 5″ (13 cm) from head to rump. They will each average the following measurements:
Head circumference: 5.5″ (140 mm)
Abdominal Circumference: 4.75″ (121 mm)
Femur Bone Length (about from the waist to knee): 0.9″ (23 mm)
Each baby is about the size of a pear.
What to Expect
Typical weight gain for Mom at this point is between 1 to 1.5 pounds/week (0.5 to 0.7kg).

What to Prepare This Week
When Mom is 17 weeks pregnant with twins, you need to remind yourself that you need to help Mom stay healthy during this pregnancy. Be her helper, assistant, and reminder of what the doctor has told her she needs to be doing. Get in this habit now so that when possible bed rest comes later, you’ve established a good routine of care.
By the time Mom reaches 17 weeks pregnant with twins, she might be feeling the babies moving around. Unfortunately, you still can’t on the outside. It is exciting to hear her describe the fluttering feeling but also disappointing when you so desperately want to feel them yourself.
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.
