I’ve always thought I was being good to the environment. I take advantage of my town’s recycling program, I use compact fluorescent light bulbs, and I take public transportation to work every day. But recently, I started to wonder if I was doing enough.

In January, my husband and I welcomed our first child–a very healthy (and very large) baby boy–into the world. The experience, no doubt, stands up to all the clich?s people rattled off to me the weeks and months before his birth–”having a baby will change your life,” “you never realized you could love something so much,” and “you’ll never sleep again.” But no one told me that having a baby changes the way you see the world, literally.
