Meow is C-A-T

I did some flash cards to teach 哥哥 spelling. I end up not using them because the results were slow and we didn't have time because these words will be tested in school.

I didn't want to waste the cards I have prepared so I used it on 妹妹 instead. And boy was I surprised when I heard her saying "c-a-t, cat" few days ago out of the blue! I asked her again but she refused to say it again. Wow! Wow! Wow! Can't wait for her to spell to me again.
