I'm so sorry you are navigating this, LT.

For what it's worth, it seems unlikely that they would transfer D based on one suspension.
It's frustrating to hear that 1:1 support isn't an option for her, as it would be a very useful tool in this scenario.

I appreciate that D being seen to lash out in this way is a risk, but I really hope there's a more accommodating solution to be found.

Is there someone available with the expertise to find out what the root of the behaviour might be?

I hope the parenting T is still in the picture, because she might have some suggestions.
