I agree that SS can make things worse and that is the reason I have to stopped to think about this first.
The previous reports have come from several different sources (none from me) including a family member, school, an angry ex, and possibly the ex’s new girlfriend. I think there was also an A&E report a long time ago for a broken wrist. Some reports may have been unjustified but in my opinion there are definitely at least some that were justified.
I do think they have been neglected in several ways - they live in unhygienic conditions, subsist on junk food, frequently left alone, rarely supervised, largely ignored, they have witnessed domestic violence (and now appear to be committing it themselves).
But my concern is what SS might do and how that might make life even harder for them.
Given that it is violence between siblings, would they be split up with one sent to live with Dad and the other staying with Mum? Because Mum would definitely blame the Younger Sister if Big Brother were sent away. I do get the impression that Big Brother is the favored child and husband substitute.
Or would they all be packed up and sent to Dad? Possibly a better option because Mum can’t blame a remaining child that way. But the violence may continue if they are still together. (Although there are more rules at Dad’s house apparently which, I think, leads to them behaving better there).
I don’t think it would be obvious that I made the report because there are other people who will eventually hear about this (school, family members, ex husband). But even if I could be identified, I will still report if I think it is a better option.
I really just want to understand what might happen, best and worse case scenario, before I decide if I should or not.
