Do as I say, not as I do

I realized I gotta, I mean, have to shape up if I wanna, I mean, want to lead by example. This I realized when my special baby started say "yeah" instead of "yes." I imagined a conversation with a future English teacher who gives my special child a bad grade, telling her I'm a native speaker English professor, her critisizing my English, and me saying "Oh yeah, wanna fight about it?"
