I agree with you, OP.
My children are 13 & 10. We live less than a mile from both the primary & high school they now go to.
At primary school, a childminder walked them to school. My youngest is in year 6, & still does this. I do allow her to walk around a third of the way home with a friend, but then I meet her for the rest of the way. She can go into a shop on her own, but I’ll be outside. She is year 6.
My eldest didn’t walk to/from school alone until year 9 (this school year). Before that, I dropped her at her friend’s house on my way to the CM & then onto work. She went back to her friend’s after school where I collected her from. That was in year 7.
Year 8, mornings were the same, but she walked home from her friend’s. If her friend wasn’t at school, I collected her from school.
During the first lockdown, whilst she was in year 8, & once they could meet up, we allowed her to meet up with her friends. So there seemed little point in mot allowing more freedom to/from school.
Now in year 9, she walks to & from school, via her friend’s house (doesn’t go in).
My youngest has asking to go to the park with her friends. It’s a 10 minute walk away, so her request has been denied. She can still go, I just cramp her style.
All her other friends are there, & I am the only parent. I don’t know if she’s embarrassed, but she has two choices. Me staying at home is not one of them.
