I’m a planner by nature, so when we found out at 18 weeks there were two boys in my huge belly, I needed to know the answer to one question – are they fraternal or identical? My boys were in separate sacs with separate placentas, so an ultrasound was inconclusive. In addition to my twin pregnancy reading, I also read articles about the pros and cons of knowing zygosity. I came to the conclusion I wanted to definitely know their zygosity.
When the boys were born, they didn’t look anything alike. At all. We painted Nate’s toenail in the NICU as a precaution but we never re-painted it because no one ever got them confused. By the time the placenta test came back inconclusive, we knew in our hearts they were not identical but I needed scientific proof. We ordered DNA tests and got to play CSI at home. As expected, the results came back and the boys are fraternal.
Shortly after the boys turned one, a crazy thing happened. Nate’s baby hair fell out and in came blond hair. Alex’s eyes turned from blue to brown. I now have one blond hair blue-eyed boy and one brown hair brown-eyed boy. There is no question on their zygosity. However, I’m still glad we did the DNA test. It just would have been nice to save the $175 in an already expensive year!
