I just randomly picked up this book at a Toys R' Us sale and am so glad I did.
I Love You Through and Through by Bernadette Rossetti-Shustak
describes how I love Logan through and through. The 2nd and 3rd page reads, "I love your top side. I love your bottom side." The illustrations are large and darling. It is such a simple book, but one Logan wants brings me to read over and over again. It's also nice because the actual book is very kid friendly and will not tear or rip as Logan "reads" it to himself. This is one of my favorites.
