History of the Cake Smash from a NJ Photographer

Since I am the biggest history nerd on the planet, yup, I totally am. I decided to write a little  piece on the history of the 1st birthday cake smash! I'm a huge South Jersey history buff, but why not include some photography history? I'm sure a lot of you will ask this... but where in the hay did this cake smash tradition come from? It seems to have had a BIG, I mean ENORMOUS, following within the last 6 or so years.
