For Delia's 2nd birthday earlier this summer, my mom got her a book called "Funny Face". It tells a story about a little boy, and on each page his emotion changes, and he makes a different face. Delia loves it. We read it at almost every nap and bedtime. She's done the faces so many times along with the book that now she's do them on command..
On the last page, there is a mirror, and the caption, "Who can make the funniest face?" Here is Dede's signature funny face.
