During orientation with the new teacher, she explained that the first week of school, we were welcome to walk the kids into the classroom to help them get acclimated but by week 2, we were strongly urged to let our kids walk into the classroom on their own. Of course, some parents probably haven't been able to let that happen yet but we were already at this place last year so it didn't take Iz long to acclimate this year. In fact, she wouldn't even LET us come into the classroom on the first day. She kindly blocked me with her hand when I went to follow behind her into the classroom. She told me, "No, Mommy, I can do it."
A week later and I wanted to fast-track the drop-off process to get to the place we were at the end of last year. I would walk her into the school building but let her walk the long halls to her classroom on her own. It pained me to watch her turn the corner where I couldn't see her any longer, but I slowly adjusted, even if she was adjusting leaps and bounds ahead of schedule.
We started just our second week of First Grade yesterday. I drove her to school and only walked her inside the school walls and let her meander to class on her own. She did great. I did too. Only one lonely tear slid down my cheek but thankfully I had my big sunglasses that day so nary a person probably noticed.
Today, we took it a step further and we did the car drop-off line for the first time. This is where you pull up into a special drop-off car lane and some 5th grader opens the door for your kid, helps them out with their bookbag, and closes the door for them making sure they make it to the sidewalk safely which will usher them into their institute of learning.

Such a brave girl, there was no crying today on this big "first" step. And Izzi didn't cry either...
