24 to 27 weeks pregnant with twins or multiples

Happy viability milestone! Because early delivery is much more common for twins and multiples than it is for singleton pregnancy, viability milestones become that much more important. Around this time, your little ones’ lungs have started to make surfactant, a substance that will help their lungs expand when they’re out in the open air.

Most babies born around this time will need to spend an average of about three months in the NICU after birth. It’s definitely ideal for babies to grow and develop in the womb a while longer, but meeting this milestone means that, whatever happens next, your little ones’ chances of good health in the future have just increased significantly.

In the next month, your babies will start to respond to sound. By the time they’re born, they’ll be familiar with the sound of your voice! Some parents find that if they start playing music for their babies during pregnancy, their little ones respond to these songs as if they recognize them after birth.

Twin or multiple pregnancy in the twenty-fourth week

If you’ve been pregnant before, you may have noticed that you’re growing significantly bigger than you might have during a previous, single pregnancy. You may also find yourself growing faster, or if you felt like you were growing at a comparable rate, that it just hasn’t slowed down when you expected it to. This is a perfectly normal consequence of having two (or more!) babies developing in there, instead of just one.

This growth may lead to even more fatigue than you might have felt during a previous pregnancy. Your healthcare provider may recommend an increased amount of rest throughout the rest of your pregnancy. Other side effects of this increase in size might include back aches or hemorrhoids.

Around the twenty-sixth week of your pregnancy, your doctor may recommend that you start counting your babies’ kicks.
