After reading Chicka Chicka Boom Boom before our quiet time today, I used the alphabet page at the end of the book to spell First Daughter's name. Then we spelled First Son's name. Then I spelled my name, which I knew would be tricky.
First Daughter answered first, even though she's still hasn't quite made the leap to the concept of letters spelling words (nor can she name all the letters if I were to point to them out of order). She made a valiant guess, though.
