We were watching the news tonight and saw a feature on language between multiples. They said about 40 percent of multiples share a language. See the clip below:
Zach and I have observed about three different versions of twin language with Brooks and Adlyn. When they were less than a year old, they communicated using a series of grunts. They would go back and forth with their grunting, and were clearly communicating something that was foreign to us.
Then, a lot of their communication was non-verbal. Rather a series of gestures.
Since last summer, they have been communicating to each other by saying, "Ah-nuh, ah-nuh, ah-nuh." Then the other would respond, "Nooooo." They will repeat that pattern several times. In the past couple of months it has changed slightly. One will say, "Ah-nuh, ah-nuh, ah-nuh, this!" The other will repeat the same phrase. Zach and I have been trying to figure it out, but can't! After they communicate, we will ask them what it means, and they won't say.
It is an interesting event to watch, something that many people may never experience.
