Here’s what I replied to a parent who asked about the Emotional Awareness Workshop. These are ran in school holidays for parent/carers and their children.

I think the best place to start is to acknowledge the difference in dynamic of the sibling relationship, which is unlike no other. They have no choice but to spend a lot of time together and unlike the relationship with the parent or carer, their survival doesn’t depend on their attachment; so there’s nothing lost when one upsets the other.
