Of course, Zelda has been able to pronounce Mamma and Pappa for a while, now, but her first proper word (which can be a rough pronunciation of the Swedish “lampa”, or the English equivalent) has been “lamp”, along with a raised hand in the air. At first it was no more than an action accompanying the word, but now she is able to point out, or look at, a lamp in the vicinity.
More impressively, she is also able to mimic my farting.
