Here’s what to expect when you are 24 weeks pregnant with twins:
By 24 weeks in the twin pregnancy your twins are about 12 inches tall (30 cm) from head to foot and each weighs 1.25 pounds (0.5 kg). Each baby will average the following measurements:
Head circumference: 9″ (223mm)
Abdominal Circumference: 8″ (200mm) which is about the same as a tennis ball
Femur Bone Length (from waist to knee): 1.75″ (45mm) which is about the same as the width (diameter) of a golf ball
Each baby is about the length of an ear of corn.

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 25 to 38 pounds (11.3 to 17.2kg).
Mom will start having stretch marks as her skin expands with the growing babies.
