You now have 3 goals:-
1/ To be removed from any child protection nonsense, (section 47 - NEVER agree to voluntary care under this one. If they mention it get legal advice asap!)
2/ To be formally ideentified as having a child in need (eg a child with a disbility who needs support) and therefore help from the disabilities team.
3/ To get any help SS MAY be able to offer genuinely and for them to p££ss off sharpish if they can't give any REAL USEFUL assistance.
Ask the social worker when she comes round for a carers assessment and a child in need assessment. Invite to EVERY school meeting etc for "support". Find some services in your area that you feel would benefit your child e.g horse riding, medical therapies, respite, childcare, help getting a referral to an alternative pead? Make it a wishlist par excellence. Aim to send her away from her her first visit with a written "to do list" of stuff for you. Make an OFFICIAL request to be referred to the disability team.
Be polite at all times - VERY polite - I can't stress this bit enough!
Keep a written record of the meeting, send emails summarising any phone conversations.
She'll go back - ask her boss to pay for some of the stuff on the wish list, write a report critcising you for some inane aspect of your parenting (I left cupcakes on the side to cool uncovered) so that it looks like she's "done her job". Second visit she'll probably tell you that you can't have anything from your wish list (however you may just get a pleasant suprise) due to "funding cuts".
Social services will send you an official notification that there are "no safeguarding issues at this time" and you'll never hear from them again.
It may be that the pead has referred you to the disabilities team for social services - check as if she has this could be the start of you actually getting some help so don't panic. This could be a good thing! Ring her secretary and ask - is the referral child protection (sometimes called safeguarding) or to the disabilities team before you get upset.
If it's child protection however follow my advice above, and have the details of a decent lawyer ready. It's a common way of bullying sen parents - my crime was applying to tribunal. If they really think a kid is at real immediate risk the police have the power to kick in the door and take em so from that simple fact you know you have nought to fret about. It's just part of the "process". Still hurts though I know.
When it's all calmed down change peads ; )
