I get what you’re saying mate, I really do. I’ve worked with a lot of kids in some pretty messed up situations, post death, sexual abuse etc etc
I don’t know the right answer on this one, and I agree it needs thinking through and being sensitive about.
Might be that they just come down for the one day etc
But trust me, nothing will be rushed into or done without thought and I very much agree with your fears / concerns.
We will have to play it by ear at the time, but I don’t think I can flat out say ‘no you can’t go I’m not taking you’ to two kids like that.
