I waited until Tuesday afternoon and couldn't bear it any longer, so called the family finding social worker. She was in the middle of something important but didn't mind giving me a quick update :D
She had gone to the meeting the previous Friday to request that separate placements be sought for the girls. They came back with the decision that they must continue to look for a family to place both girls together until April (although she said she wanted to spend this time ruling out all families as she didn't think it was in the girls' best interests).
She explained that calling my link worker was on her list of things to do, and she would get round to it in the next week or so. And once they've spoken she wants to arrange to visit me with the girls' social worker. This will hopefully be sometime this month.
It seems to me that she is quite keen to meet me about the older girl, and also said that perhaps I'd impress them enough that they'd consider me for both girls together.
So I'm going to do everything I can to impress them. She mentioned therapeutic parenting, so I've ordered books on this. She's spoken about the sibling bond so I'm looking into that too. I've gone through their profile and noted how I'd match each of the points. I've called local schools to see where there are spaces, I'm going to write up lists of things to do and places to visit, I'm printing out houserules and daily timetables so they know I'm organised and can manage with three children.
And if anyone has any thoughts, ideas, online articles, book recommendations, anything to help me get my girls, please let me know! :D
