Are you a lover of music (or all things Apple)? What a cute idea to be an iPod (or iPad, even)! Check it out over at LilSugar.com. This would be cute for a little one, a grown up, or even the whole family. I'm thinking different Apple products or even the different generations of iPods!

Do you have a new baby that will be sleeping anyway? Why not swaddle them up and make them into a baby sushi roll! So cute!
