In the past two months, Wonder Twins have identified a white, Carterâ€™s hooded towel with blue trimming as the security blanket. Luckily, I have two, which greatly minimizes the head slapping (of each other, not themselves). The whole process is totally like when a wand chooses a wizard in Harry Potter. Out of all the soft blankets we have in the house, really? You gravitate towward the secondhand ratty towels? Nice.
