PP in my experience, the benefits of FDC are so great that it's worth just paying the fee and starting to meet some carers. You don't have to accept the first carer they give you. Both of my DDs *never* cried when I left them in FDC but the few times i put them in a centre (out of necessity) it was always traumatic for them.

Also, the registration fee is more than offset when you consider that if you try her at another centre, you may end up paying 2 weeks notice that you don't use (if it doesn't work out).
