As I was putting the remote in the refrigerator, I stopped to think about how motherhood has changed my brain. It’s not temporary, though it is worse when your child is a baby, at least from my experience. I forget words—I’ll point at the couch and say, “Get your jacket off the—um, the…” and snap my fingers as if it will come to me. My husband, who has never missed a night of sleep from post-hospital parenting, prods, “Couch?” and sometimes I just want to smack him.
