A friend (work colleague really rather than friend) has just posted some mawkish shite about CIO and that she is "anti" it.
I wouldn't do CIO though we did use CC.
However, the thing that annoys me is, if you are "anti" a parenting technique, just don't do it. No one is forcing you to. You can parent your child any way you like. Why post about it on facebook? Just do what works for you and get on with your life FFS.
