Teagan says her "ABCD's"

Last weekend when I was reading Teagan the Dr. Suess ABC book, she asked me to sing it. I sang her the alphabet song and she immediately loved it. After singing it to her for about a week, she totally surprised me yesterday by singing the entire alphabet all by herself! It always cracks me up at the end when she says "Now I know my ABCD's". So, Teagan doesn't sing the ABC's, she sings the ABCD's.
