These days, I’m wearing a futuristic wrist brace due to overuse of my left thumb, AKA De Quervain’s tendinitis, AKA “mommy thumb.” The problem is, I’ve been picking up Della under her arms, with my thumbs and forefingers, instead of placing a hand under her head and another under her bottom. Or whatever. I think “mommy thumb” could also be caused by thumb-scrolling through Internet baby forums, such as BabyCenter.com, whose app I deleted yesterday for the sake of my health. But I’m thinking about reinstalling it.
