PreS-Gr 1 Ben is counting down the days to his fifth birthday, but sister Molly is surly about Ben's upcoming celebration. On the day of Ben's party, Molly announces that she won't be able to attend. Mother resolves the problem by pointing out that Molly's birthday will be coming soon. Molly does attend the party with some special presents for Ben, including a letter that states, ``I'm happy today is your birthday because now we don't have to count the days to your birthday any more. Now we can start counting the days to my birthday.'' Although Molly has given some thought and care to Ben's gifts, it is the letter that will leave the final impression on readers. While the opaque watercolors adequately illustrate the text, sibling rivalry over a birthday is dealt with better in Russell Hoban's A Birthday for Frances (Harper, 1968), as it possesses a charm and a warmth lacking in Russo's book and shows Frances' emotional growth.
