Make Your Own Alphabet Book
Kodakgallery.com and other online photo services offer a great opportunity to make customized alphabet books for your toddler. You can fill the book with your favorite photos of people and things that your child loves, corresponding with each letter of the alphabet. I created one for my daughter ("A is for your cousin Ava, B is for bathtime, C is for carrots, D is for Daddy, etc.") and she loved having a book that she could "read" at an early age, just by recognizing the pictures.
Of course, after having created mine on kodakgallery, I discovered that shutterfly.com has a special The ABCs of You design that would've made the whole project so much easier. Oh, well - next time.
