one of my favorite books is called "how many kisses do you want tonight?" it goes through 10 different animals & 2 children -- each baby is asked that same question. they respond with one kiss, two kisses, and so on. one of the pages is about a daddy snake & a baby snake. mommy reads that page like this: "how many kissssessss do you want little guy? daddy ssssnake hissssessss to little sssssnake sssshy. i want nine, he ssssayssss with a sssssmile, ssssslithering into hissss grasssssy pile." so i have learned that the snake says "ssssss." one day i brought this book to mommy with it opened to the snake page & i was just hissing away! now i find the snake page all by myself. i love it!
