I enjoyed reading this article. I mostly agree with her and yet at the same time, I imagine it might be a whole lot easier to be this hands off mom when she knows her kids are on her campus (even if she doesn't see them she knows she can if she really wanted to).
I have sympathy for parents that find this too hard to do and not sure how I will be, but I do think it's how it should be. And my heart breaks for that mom who sits for hours looking at the college cam for her son. That seems beyond helicoptering to something that needs professional help.
