We had a post a while back about twins calling each other by one name. I don't want to search for that post, so I created a new one. My question is: How long did it last?
Both of my girls are "Nina." Technically, they are trying to say "Fina." However, they cannot say they /f/ sound, so it comes out like /n/. It confuses other people, but we understand what they mean. That is all that really matters. We just make sure to specify that the one "Nina" is really "Keira" and hope that they will get it in a few months. Sarafina used to call K, "Kee-ka." That stopped once K started using "Nina." Then, they both became the one name. They even identify themselves in pictures that way! K can see a picture of herself, but it is "Nina." Gotta love twins!
