Major regression

"Gadadaba wawa", that's typical Nathan talk these days. He pretends to be a baby and copies many things that Evan does (to get extra attention most likely). Instead of using words, he's going back to signing as well, "Evan style". For example, the proper way to sign "more" is fingers to together, and Nathan knows that. But because Evan signs more by clapping hands, Nathan is also clapping "more" now.
