We did end up using the idea of taking her out to the car - which we have not actually had to do. The mere threat of it has freaked her out, especially when we start getting the keys. Some of the posts here also made me get real about our own role in this, and we started new "house rules" that made it clear that loudness was unacceptable. After doing that for about a week, I reached out to my neighbor directly and asked her if she noticed any difference. She said it was much better, and we talked about me checking in with her every once in a while to see how the noise is from her perspective.
Also, may I say that I was not fair to describe the noise as "screaming at the top of her lungs." That happened a few times, but it wasn't the norm.
I found many of the comments here judgmental and unhelpful, like the suggestion that we should somehow "move to a house," which we can't afford, or that I should not have another child, which is just cold. But just as many of the comments were useful and compassionate. So thank you.
I still don't know what the law says, but it seems like it's going to be ok, for my neighbor and for us.
Great news for all of you-you, your dd, your new baby, your neighbor! I'm glad you were able to find some useful info in this discussion.
