Bathsheba, I would say let the year begin and monitor the situation closley. Maybe make an appointment with the teacher to ensure she is aware of your daughters hearing problem, and why she will ask more questions.
One way of monitoring the situation is to try and do a bit of in class help at the beginning of the year, I know it is tough as you have another child and you are pregnant, but at least you will be able to monitor first hand. If after the first couple of weeks at school you are still unhappy then make the request to move your daughter.
Give young dynamic teachers a go, as this is what I got labelled by the other staff when I started my job last year, because I wanted to try new things, and do things a little bit differently- but at the end of the day, I had one of the highest rates or attendence over the year, my kids all learnt something over the year, and I had challenging behaviour problems under control within weeks.

But at the end of the day it comes down to doing what makes you and your daughter comfortable- and if something is not right and your daughter is not learning, then you are well within your rights to say something and insist on a change!
