Both parents
This one can’t be won by outlasting the other parent
Research on why children leave therapy early keeps landing on the adults around it. A meta-analytic review of dropout in child and adolescent outpatient mental health care found that how a parent sees the treatment — whether it seems relevant, whether it seems worth the obstacles — predicts premature termination. Children are not sealed off from that.

That has a consequence for each of you, and it isn’t the same consequence.
If you’re the one fighting to keep it going:therapy that runs against the other parent’s active opposition is not the treatment you think you’re paying for. Winning the argument and getting the appointments back on the calendar are not the same as getting the benefit.
If you’re the one who wants it to stop:staying quiet is not neutrality. Your child is already reading your position. You don’t have to endorse something you have doubts about — but the doubt is in the room whether or not you voice it.
Which is why this decision has to be actually agreed. If it’s imposed, the thing you’re fighting over stops working.
