Mysterious conversation of 18-month-old twins

A recent video of two babbling boys babbling in the kitchen has caused scientists to wonder - what are they talking about, at this new age of 18 months?

Other twins eggs Sam and Ren (Americans) seem to be having a complete conversation with questions, answers, facial expressions and gestures, even loud laughter. But they really haven't said a word yet.

" These babies are at the top of the language, " said Stephen Camarata, professor of hearing and language sciences at Vanderbilt Kennedy Center (USA), commenting on ABC.

Instead of emitting words, the two boys are creating sounds with distinct pitches and rhythms.

" They use very standard sentence models. That's a way children learn to speak. Just before they can pronounce words, they know how to talk, " Camatara commented.

Many other experts also commented that the two boys have similar development, and seem to have a common understanding of a problem, even if their audience may not. It is as if it is common for couples to get married for a long time, they have many things in common and there are things that need not be said or exchanged very little.

In more rare cases, twins have developed mysterious languages ​​between them that only they can understand each other. Catherine Brady, the mother of the twins and Austin eggs and Landon Grant, about to be 5 years old, said she sometimes struggled to translate the " twin language " of her two children.
