Nic I have been thinking about your post all evening and I honestly can't decide what to think. I haven't seen the blog but I kind of want to know more. More about that family. Where they live, how they spend their days, what the temperaments of the children are like, what is she like? I wonder if she was raised with similar methods? If she has made a truly informed choice to parent this way or if she is (as so many of us do unconsciously) repeating what she experienced as a child? Is she in an abusive relationship where she is punished and held accountable for the misbehaviour of her children? Does she have particular personality traits that predispose her to getting pleasure from controlling others or inflicting pain? How do her children interpret/respond to her behaviour? Is there more "clear cut" abuse going on at other times or is this the only situation that borders on abusive or taking punishment too far?
I am reluctant to judge her without much more information. I am curious to know more. I wonder how she views her children and what her philosophy of childhood is.
