If you run a charity you only get funding on the basis that x or y is achieved and a lot of what KC achieves is, by its very nature, unquantifiable. That doesn't meant it isn't worth doing.
How do you "measure" suicide prevention exactly? The child concerned may not go on to 'succeed' in life by everyone's else's definition of the word, but for them, simply existing is an achievement. (This may sound over-dramatic but I am using a rl example from my sister's charity.)
Obviously, they need a robust accounting system and all funds received need to be accounted for, but the very nature of the end-user she is dealing with makes "effectiveness" very difficult indeed to quantify.
It's evident on Mumsnet sn threads how much parents contribute in terms of endless meetings with mental health services, statementing, teachers, doctors etc (aside from parenting) the task is difficult and seemingly never-ending.
Imagine the fate of a child with sn with no supportive parents (who is by definition more likely to have mh issues precisely because of its particular circumstances).
CB has made herself unpopular with the establishment because her approach is unusual. She initially tried to help children whose parents were unable to bring them to therapeutic appts. Then she helped children who self -refer: that in itself leads to funding difficulties because they do not come under the umbrella of any particular body.
She has talked about 'love' and lack of love in the care system - something no one wants to here - but is fundamental to a child's development.
She has also re-mortgaged her own flat twice in order to keep the charity going in its early days - so to call her a rich hypocrite is totally out of order.
I don't claim to know whether the accusations against CB and KC are correct or not - I sincerely hope they are not - and there are obviously many people on here who have more direct knowledge than me.
But I think it's easy to sit in front of the computer and criticise someone who has, for 19 years, sincerely tried to make a difference.
