So - pristine photos.
That night, we had a few friends over for birthday dinner and a red velvet bakery cake from The Velvet Bake Shop (located in Plano, totally totally awesome!). I'm thinking "OK, well, we'll take a quick shot of her with her slice of cake, then I'll eat it since she doesn't like cake." I get the shot, leave the room to put down the camera, come back and she is totally going to town on the cake! Loved it and ate every last crumb. Well, every last crumb that wasn't adorning some part of her body anyway. It was a very red-velvety bath that night.
So - I am left to conclude that Zoe just doesn't like cheap cake. That's my foodie girl :)
