I’ve realised neither the police officer or the social worker gave me any contact details, they said they would at the start but we clearly all forgot- I don’t have an incident number either. They said they’d contact me tomorrow so I will have to hope that that’s the case.
Please take the lead on this and contact them now to request that - you can call whoever you called initially and they can work out who came out to you, you can't just sit and hope they get in touch.
I'm very surprised they haven't organised or suggested any counselling or at least a further visit to assess if your daughter may need further help.
She likely will in the future because as she herself becomes aware of what is normal / acceptable with regards to sexual feelings, she will likely have a sort of second wave of disgust at her brother and due to their ages that's also likely to coincide with her going through puberty and him being a teenager.
From someone who has been there, please don't think that because she at this moment doesn't realise the implications of this she won't be just as affected later on.
The only way I can try to explain it is you thinking about your initial reaction when you thought about what he actually did - then imagine her realising that's happened to her, by him. I feel awkward and try too hard to be 'normal' around him which makes me feel embarrassed and sad as his shame and awkwardness about what happens manifests itself in a total rejection of me and refusal to relax around me and treat me nicely. He can't get too close as I know too much sort of thing. It's awful.
And I'm in my early thirties now. It was all about him and his struggle, because people thought I wouldn't understand what had happened. I didn't at the time but I do now.
Ask for help, ask for resources, ask for a plan to manage this - start today by calling whoever you called initially and insisting you get contact details of whoever came over.
I feel for you and find it hard not to feel angry for your little girl, not angry at you, but angry she has this burden now.
Please be there for her always
