Mabel kept hitting Storey's CD player while Storey was memorizing the entire script of "Into the Woods" (she's Milky White, the cow, with no lines of her own so she's taken it upon herself to learn everyone elses parts). We have been using "uh oh" instead of "no" (the attachment therapist suggested not saying "no" for the first few months), but Mabel continued hitting the CD player, making the CD skip/stop and Storey upset.
So we put Mabel in a "time in" (another thing suggested by our therapist). Zak had her fold her arms and sit for about 30 seconds. Just long enough for me to snap a picture. It was adorable.
