HEADCANON #3
Izumi, Akemi, Kenoa, and Ronin have pretty typical first words ("Dada" & "Mama")
Kya II's first word is "Oogies," thanks to her Dad's constant teasing of her Aunt Katara and Uncle Zuko (Sokka is embarrassed, especially since she clearly thinks it's his name; Katara finds the whole thing hilarious)
Bumi II's first words are "Yip Yip" (Aang couldn't be prouder; the GAang thinks it's cute)
Ryu's first word is "Umi," thanks to his inability to say "Izumi" at that age (This becomes Izumi's nickname amongst her siblings & cousins; Zuko ad Iroh call her "Lotus Blossom"; Iroh calls her "My Favorite Fire Lord" when she's a teen; Sokka calls her "Zum Zum"; Toph calls her "Sparky Jr." from day 1)
Jingyuan's first word is "Shit." No one wonders which parent he got that one from. (He says it at an international summit with his Dad, and his Uncles Zuko and Sokka in attendance; Aang is mortified and apologizes profusely to all present; Sokka laughs so hard he cries and falls out of his chair; Zuko spits out his tea all over the Earth King, he laughs so hard; Toph cackles and snorts when they tell her afterwards, completely unashamed just amused and proud)
Yua's first word is "Moo." (Her parents are confused at first, until they realize she yells it particularly animatedly at her PaPa, who calls her "My Little Moon and Stars")
Tenzin's first word is "Momo." (Toph says that's close enough to "Mama," so that means 2 out of 3 kids chose her as their first word, so she wins -- even though Aang is unaware of them ever being in a competition over that)
