Do All Babies Do This?

Years and years ago I purchased an Anne Geddes photo book and the above picture was one of my favorites of the book.  I dreamed of the day when I would have my very own little one in order to recreate this photo.  Now, I didn't go all out with it as you can tell below.  We went for a simple version.  J loves to look at his belly.  He pulls it up as much as possible in hopes of sneaking a peek at his belly button.
