Here’s what to expect when you are 22 weeks pregnant with twins:
By 22 weeks in the twin pregnancy your twins are about 11″ (28 cm) long from head to foot. They will each average the following measurements:
Head circumference: 8″ (198mm) which is about the same as a tennis ball
Abdominal Circumference: 7″ (175mm)
Femur Bone Length (from waist to knee): 1.5″ (38mm) or about the same as the width (diameter) of a toilet paper roll
Each baby is about the size of a papaya or spaghetti squash.
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).
Total weight gain for the twin pregnancy so far will average between 23 to 34 pounds (10.4 to 15.4kg).

Kimberly H. – “22 weeks. So far so good. Just tired a lot.”
By the time my wife was 22 weeks pregnant with twins, I could feel the babies moving if I put my hand on her belly. Being able to feel your unborn children moving is an amazing experience. Before, I could only see her growing belly and the ultrasounds. Feeling the babies move really makes the twin pregnancy tangible.
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.
