There's some good advice/knowledge on here.
Not a SW, but I go to cp conferences regularly.
Pp was right - there will be LOTS of people at the conference (ICPC? - initial child protection conference).
If it goes to CP or CIN you will be allocated a SW, probably not the one who has been working with you up to now.
At the conference, everyone will be looking to see whether you're putting your child first or not.
The more you put your child first, the more they'll relax around you.
Take it very seriously. It is VERY serious. If it does go to CP, if they're not happy with you (i.e
If they feel the need to escalate), the next step is taking your child away.
If it goes to CIN, it's less serious, but still take it seriously.
Be prepared to take what they say on board OR to have v sensible/logical/practical reasons why not.
