It may sting when your daughter ducks as she sees you at school. Keep smiling, though. This is not a reflection of you as a person or a mom, but rather, part of the very normal developmental stage she’s going through. And, at school she has a separate identity without you. “So take a deep breath and remind yourself that you used to be 12 once and probably felt the same way about your own parents,” advises Stephanie Mihalas, a child psychologist in Los Angeles.
