My mom used to walk me to school maybe until I was 7. Then we moved to an apartment and I walked to school with at least 2 other kids, up through middle school. In high school, I walked by myself.
I drove today during school hours and saw quite a few elementary kiddos walking by themselves. I'm sure their home was only a few blocks away though. I think I will definitely walk with my LO or drive her until high school!
