Quoting Mama*AtoZ:" What were your reasons for home schooling? I can't fully agree about respecting her wanting to go and ... [snip!] ... that age. The decision may be more reversible where you are though, so i can see that changing my opinion but only slightly. "
We are doing part time, 2 afternoons a week for 2 1/2-3 hours, not several hours every day. Also, I just don't think that school is as harmful as you think that it is. It all depends on the child's personality and learning style. If we choose a school that matches her personality and learning style, along with our parenting style (Reggio schools do not use punishments, for example), it will not be an issue, especially for only a few hours per week.
I think that we have very different views of how in control of their lives our kids should be. Probably based on spending time with our individual kids and knowing them each very well. I think A does understand, we talk about school, we role play "school" a lot, she pretends to go to school every day. She watches shows about school, etc.
I let her have the reigns in every possible area and she does extremely well with control of her life. I feel that I am respecting her by not only letting her choose her successes, but also letting her make her own mistakes. If school is a mistake for her, then she will know firsthand. But I won't take away a safe opportunity she wants to take just because I have decided it is not right for her, that is not my place. I think that would build resentment in our relationship.
