Chaos, Wonder and the Spiritual Adventure of Parenting: An Anthology

I'd been warned that the day would dawn when my sweet, tractable daughter would become a Terrible Two. And still this entirely predictable thing broadsided me, because in the beginning she was mine-as much a part of my body, literally, as my own arms and legs. The milk I drank knit her bones in place, and her hiccups jarred me awake at night. Children come to us as a dramatic coup of the body's fine inner will, and the process of sorting out "self" from "other" is so gradual as to be invisible to a mother's naked soul. In our hearts, we can't expect one of our own limbs to stand up one day and announce its own agenda. It's too much like a Stephen King novel.
