This is more of the heart-warming than transcendent variety, but it is a sort of rite of passage for both myself and my daughter.
My daughter goes to a Montessori school. If you want me to talk your ear off, ask me about it sometime. She'll be six at the end of May, so for the past four weeks she's been visiting at the elementary school, one day a week on Tuesdays. One of the beauties of the Montessori system is that kids are allowed to transition like that, spend one day a week for two months, or three mornings a week for two weeks, or however long it takes for them to be ready to completely transition.
It's a big step. The first morning when we went to the classroom, two older girls rushed up to my daughter and one asked her "Are you visiting?" and the other said "Here, let me show you where to put your things and let me show you around." This was completely unprompted by any teacher (in fact, we were slightly early, the teacher wasn't even in the room). I was much warmed and pleased by that, and knew I was leaving my daughter in capable, young hands.
The next day she went back to her old classroom. I stood at the doorway with her and she turned to me and said,"Mama, don't wave at me. Elementary kids don't get waved at."
We had had this long ritual where I'd drive by the classroom window and we'd blow kisses at each other and I'd hand signal I love you and pretend I was hugging her.
But she doesn't need it anymore.
That's both the awesomest sign of independence and growth, and the saddest one. I'm so proud of her for her declaration, but I can't believe the toddler/young kid cuddles are mostly gone now, so suddenly. My excitement, pleasure and nostalgia were so simultaneous and strong, I practically got vertigo.
Raising kids is not for everyone, but it's so rewarding and smacks you in the face with life lessons so often that I am thankful for the experience.
Thanks, palimpsest for starting the thread, and thanks ClintMemo for your humbling contribution and SFEley for your cryptic one.
