According to babycenter.com: The twins don't have much room to maneuver now that they're over 18 inches long and tips the scales at 5 1/4 pounds (pick up two honeydews). Because they're so snug in the womb, they aren't likely to be doing somersaults anymore, but the number of times they kick should remain about the same. their kidneys are fully developed now, and their livers can process some waste products. Most of their basic physical development are now complete — They'll spend the next few weeks putting on weight.
As you can see in the picture below, Christy's belly is looking gigantic compared to her petite body.
In the doctor's office visit laste week, a women who was near labor couldn't believe how big Christy's belly was. We're now on a twice a week office visit to monitor fetal heartbeat and make sure placenta is continuing to function normally. The twins are so cramped in the womb they keep wanting to dig under Christy's ribcage. Surprisingly Christy has been able to get some quality sleep lately. We both feel that this is the calm before the storm. The irregular contractions are still occuring but still not quite there yet. So we need to be a little more patient.. On the bright side, we still have time to fight over the names~
