How do you spell tuna?

Nora: Mommy, how do you spell tuna?
Mommy: Well, the first sound is 't'. What letter says 't'?
Nora: T
Mommy: That's right! Great job! The second letter in tuna is U, but then you hear the sound 'n', what letter makes the sound 'n'?
Nora: N
Mommy: Wow Nora! The last sound is 'uh', what letter makes the sound 'uh'?
Nora: U
Mommy: Holy crap, you know the short vowel sound for U?

I said the sounds for dog and cat...she was able to say all the letters after I made the sounds. Shocked you ask, YES!
