This morning I dropped my daughters off at school and they both walked in without looking back. This is quite a change from the beginning of the year, when my kindergartner would cling to me for dear life before I left. I had to walk her down to her classroom, help her put her backpack in her cubby, and give her a dozen hugs before leaving. After a few days of that routine, we shortened it so that her big sister walked her to the classroom, so long as I stood in the entryway where she could see me until she got to her classroom. Then when she got more comfortable with school and more self-reliant, I was able to wave at her from the doorway when she turned the corner to go to her classroom. And now she doesn’t even bother to look back. She’s on her own.
