If she'd realized others with an interest had seen her enter, Regina would have cast a glamour over herself or her wish, but she'd been distracted by her ponderings about wish magic and didn't consider it (a mistake she won't make later, when getting her fortune told). So she pays little attention to anything but the contents of her heart when she makes her wish.

Freedom for my children, and for them to know that I love them, she writes, and then because there are no instructions and no one can tell her not to, she turns over the strip and writes their initials -- HDM, RH, EQ, JK, O-EQ, O-JK, EJK, ASoW, SW/MMC. As a final impulse she adds, and any I choose in the future, especially but not only, CMcG and MH.

It's a huge wish, but since it's not really for her, she feels all right about that.
