I'm a Kindie teacher, and I get plenty of chatty kids each year. If you want to make Kindie a positive experience for your DD, help her realize what to expect.
Explain to your DD that when she goes to Kindergarten, there is a time to talk, and a time to listen.
Make sure that she understands that it is the teacher's job to do a lot of the talking so that she can help the children learn.
Work with her on not interrupting, not talking when others are talking, and waiting for her turn to talk (you may even make a game of it at dinner by raising your hands to talk!).
Talk with her about staying on topic. If the teacher is talking about the seasons, it's not time for her to talk about her new puppy.
That said, kids learn from each other by talking about what they're doing. There will be plenty of opportunities for her to talk to her classmates and her teacher. When you enter my classroom during center time, there's a happy "buzz" --- it is anything but silent!
Good luck! HTH!
