This is such a thoughtful and sweet idea for your children. I have loved this personalized words book since Liz first posted it! She took photos of things that were special or familiar to her son and then put them into a book.
I think it would be fun to make it an alphabet book, but then what do you do with letters like 'x', besides "xylophone"?! As soon as I have a better grasp on Rilo's likes/dislikes, I am most definitely making one of these!
