Thanks, @becsbuddy. That's exactly the hard part. My husband seems pretty convinced that the tantrums are just her personality and she'll be fine to get home by herself. And he might be right, I am just not sure. She locked herself out of our house yesterday and couldn't figure out how to get back in. (Could not remember the code and did not think to knock or ring the doorbell). I saw her peeking in my office window and went to get her. He's the primary decision-maker since it's his mother, and it's possible that I'm over-reacting, but I have also been home for the past 2 years while he traveled, so I watched her decline and lived with most of the tantrums.

There is a transportation service, and they would take her, stay with her, and bring her home, but she says that she doesn't want to pay for that. (Although they could afford it). I think she wants to be out on her own the way she would have been a few months ago. This is not so much about going places (because he would take her) but having the freedom to go alone and not having to be supervised.

She's so stubborn that I'm not sure I could get her to wear the bracelet but I will bring it up with him again and see if he's willing to broach the subject. Thanks for the advice.
