Well Maylie already knew her alphabet. So we'd go "what letter does Maylie start with? MMMMMMMMaylie?" and she figured those out pretty quickly, but if she didn't know it I'd answer and say "M! MMMMMMMMaylie starts with MMMMMMM!!!" So she got the obvious ones pretty quickly like D, M, T, P... and slowly with exposure to the not so obvious ones (like G, the vowels, or C/K) she knows most of the alphabet and is pretty good with it. She even remembers which words start with C and which with K.

It's something to do in the car, Maylie loves being quizzed on things and so likes the question/answer things. Sometimes she'll ask me "what letter does $word start with?" and I'll answer (but I have learned not to say the wrong answer to see if she catches it because then she'll think it's funny to give wrong answers.)

Now that she's good at the sounds the letters make at the beginning, adding more letters isn't too hard for her.
