I'm wary of wading in to a discussion which seems quite heated. However, I do have relevant experience.
DD1 was self-referred by me, to the Disability team.
Here, you had to go through the 'reception' team, in which a SW with CP remit comes to do an initial assessment. That has recently changed and now if a child is clearly qualified for the DT (e.g. Quad Cerebral Palsy, life limiting illness, etc.) then they get direct assessment by the DT.
I was seen by the reception team. The first time, I was knocked back completely and referred to 'universal services'.
I tried again 18 months later. By this stage DD1 was at special school so it was more obvious that she had significant needs. She was assessed by a CP SW, who decided that DD1 met the criteria for the Disability Team due to her needs and my inability to keep her sisters safe (she was aggressive toward them and they were both under 4).
DD1 has never been under Child Protection with Social Services and has always been a Child in Need.
All the CIN status means for us, is that our SW has to do some paperwork every so often to review her situation. We get support workers who come and either help me do an activity with all 3 girls, or just take DD1 out, as we feel is appropriate.
CIN is not an extension of, a precursor to, or a consequence of, a Child Protection status. It's completely separate. A child can be a Child in Need and also have a Child Protection Status, I believe.
Claw, I know you had a bad experience. I know there are others who have also had bad experiences. I think it's important that sazale doesn't get a message that there is some sort of skullduggery going on because she has been allocated the CIN team. It's perfectly legitimate.
