Only Child

1 I cradled my newborn daughter and felt the heartbeat pull me out of shock. She didn’t know what her hands were: she folded them. I asked her was there a place where there was no world. She didn’t know what a voice was: her lips were the shape of a nipple. 2 In the park the child says: watch me. It will not count unless you see. And she shows me the cartwheel, the skip, the tumble, the tricks performed at leisure in midair, each unknown until it is finished. At home she orders: see me eat. I watch her curl on herself, sleep; as I try to leave the dark room her dreaming voice commands me: watch. 3 Always we passed the seesaw on the way to the swings but tonight I remember the principle of the lever, I sit the child at one end, I sit near the center, the fulcrum, at once she has power to lift me off the earth and keep me suspended by her tiny weight, she laughing, I stunned at the power of the formula.
