I just had a thought. Is there something special that your daughter wants to do that involves leaving the house, like a trip, or something like an arts and crafts project that you need to get the supplies for? I'm sure you have already probably talked this over with her therapist, but if there is something like that she can work towards, that will get her out of the house maybe? Like, she can have beading/sewing/painting supplies but only if she comes to the store with you to pick them out? I'm probably reaching here, but thought I'd toss that out there.
