Well, we have had that exciting initial visit! I went mad cleaning the house, every where I could except our bedroom, which is always the last place to see a duster or hoover! The social worker arrived, a very nice woman of about my age with nice taste in jewellery. I am not sure exactly how nervous I was. There were all kinds of things I thought that might potentially make us look less ?good? as adopters or might make things uneasy between me and the new social worker! I?m overweight so I wondered if she was thinking about my size (I am losing weight slowly! So there will be less of me next time she sees me!). Our house is very ?un-flashy?, rather tired looking and a bit cluttered! We have a DD who is adorable but can be a handful at times and I wondered if they would ask much about her at this stage, I wanted to be honest about her but also didn?t want to make mountains out of molehills (because she is a normal, happy little girl who also gets upset and angry at times and I just was not sure how much to talk about her!). Also we?re Christians and sometimes people say social workers aren?t as keen on Christians (yes, I know that is not true and she only asked us one question about faith and seemed very unconcerned about that at all), and just for the record asked me nothing about my weight!
She didn?t ask for a glass of water or to use the loo, as I had been led to believe she would! 
She did drink our coffee and said it was very good (well done Sainsburies Basics!) and she even had a biscuit (carefully selected Foxes chocolate shortbread - YUM) ? I mean carefully selected by me not her!
My hubby had said I didn?t need to clean the house, she wouldn?t look round. And all the other stuff I had read seemed to suggest that she would not ask to look around.... but she did! She asked if we had room for a child and when I said ?Yes?, she asked if she could look around. Of course we said ?Yes?! She looked everywhere except our bedroom. I just asked ?Do you need to see our room? It?s very untidy!? And she said ?No.? Result!
Anyway, sorry for the minutia of details. I am just delighted it all went well. She is happy for us to go to the next step, training in January.
Thanks for all the encouragement.
