I don't completely disagree with human interaction having a play with this, in fact I've even included it as a possible problem/solution. I'm just concerned that, since OP needs to fix the basics of their husbandry and their parent's participation with understanding it, it's probably best not to focus on bonding yet. Your suggested methods to calm their bp may or may not contribute to doing the opposite, depending how handsy their parents are or how they perceive what a calm snake is, so op may need to be mindful about that.
I just think it's better we don't over complicate things for op yet.
