We need to emphasize correct letter pronunciation with Dom, but I'm a little slack. I could possibly be in denial about my little boy growing up, it just happens too quickly. Besides some of his pronunciations are hilarious...they probably won't be so funny when he is heading off to college!
Grandma, of course, is more than willing to help him in this department. "Dom, say F-F-F-F-Frog."
Dom, thinking this over responds, "Toad."
Not too bad for a just 4-year-old.
