At forty-four weeks, Jonas is: making the signs for “dog” (and paying special attention to that picture and word in his first words book) and “change diaper” (he’s still making and perfecting the signs for “eat”, “drink”, “milk”, and “more”); babbling up a storm; enjoying games of reverse keep-a-way with Petra; crawling like Thor, with one hand flat and one hand in a fist; working on his balance; clapping and waving; and giving kisses and love pats.
