The mood of my baby photos falls into one of two categories: light or dark. In the earliest days of parenthood, everything feels so miraculous, fragile and intense. It's like we're living in a safe, dark little cave with our babies for the first few months, marveling at each other and figuring each other out. As they grow, they start to show us these incredible changes in personality, and the mood shifts as we start to feel like more competent mommies and daddies. We step out of the cave and into the light.
