When older DD was in speech therapy as a child, a lot.
For IT, when she was 3-6, not at all except for a check in at the end.
For her anxiety therapy, except for the initial set up sessions, not at all except for a quick check in at the beginning or end of each session. Sometimes if they have a lot to talk about or work on, the therapist and I touch base on the phone. sste, I am really surprised that you are that involved. But older DD did not start seeing a therapist for the anxiety until she was 8, so that may be the difference. Even for CBT therapy, I think the child will not speak as freely with the therapist about fears when the parent is in the room, especially if any of the issues revolve around the parents or siblings.
For homework, I was a LOT more involved with older DD than younger DD. And with older DD I have backed way off over the last few years. I try now to only provide space and be involved as needed. I don't get involved in correcting or monitoring the homework unless my participation is needed (reading a word to her to spell, etc.).
