Congrats on your coming blessing! I can't believe you're still taking lessons when you're so far along. I mean that in an admiring way, but it must be getting a little awkward...? I hope that's not insensitive--say, if you're adopting--but I'm assuming pregnancy because you're so clear about the date. Anyway, I am absolutely positive that your teacher is NOT going to be devastated or think less of you for quitting during late pregnancy/early babyhood. In fact, she surely must be expecting to have this conversation at any moment. All you have to do is point to your tummy, smile, and say, "You know, I'd love to have one more lesson today, then after that I'm going to be busy for a while!" I mean, no one would fail to understand that. And have the final check prepared so you don't fuss around with it during the conversation; it will help you to feel more calm. If she talks to you about how to keep practicing, just smile and say, "What a good idea, that's exactly what I'll do!" When you have your wonderful baby, you can do whatever you want. I mean, maybe you'll want to play some, but maybe you won't, and there's no reason for you to feel pressured about this. I'm a teacher, and most of my friends are teachers, and not one of us would expect a student to keep a practice and lesson schedule at such a time. It's not going to be a problem. Best of luck!
