Twin Pregnancy 16 to 20 Weeks

Congratulations Mama, you're about half way through your amazing twin pregnancy! Let's see what you can expect this month:

Each fetus now appears as a fully formed, teeny tiny baby (about 8 inches or so by the 20th week). At this point, the brain is the only component that shall continuously develop throughout pregnancy. Your twins will spend the rest of their stay in the womb growing, and growing, and growing! They are starting to hear for the first time and may even react to loud noises. They will be exhibiting more coordinated movements at this time, and many believe that twins are now aware of each other as well. Imagine if this is where the twin bond actually starts. This is just so fascinating!

This is also around the time that your doctor or other healthcare professional can tell you the genders of your babies via an ultrasound or sonogram. Will they be boys, girls, or one of each? This can be super helpful when you need to plan a nursery for two, though lots of parents decide not to find out and enjoy the surprise instead!
