Thanks for your reply AJ. I contacted the school when we first split up to see if they have anything in place, but they don’t. I spoke with their teachers to keep an eye out for changes in behaviour, but other than that, there’s nothing.
I also spoke with our GP and the only support they can offer is through the local CAMHS service, which isn’t appropriate at this stage (hopefully never!).
I think I may have had a look at the Relate website a while ago but I’ll check it out again.
It really seems to be a postcode lottery as to what is out there to help children sadly.
