We started DD in a dance class in September. She will be 3 this December. She seemed ready and the dance teacher meet us and agreed. She was doing great. There are 4 little girls. ( I think who are all 3 already.) At the end of October we got to observe the class. She did not listen , stop talking, or do what the teacher asked until she was asked a couple times. ( this is not like her bahavior at home at all.) The teacher assured us that she is not normally like that. We spoke with DD about it. The last two weeks I have taken her and she has also not stopped talking during class. ( the other little girls do not seem to talk at all even when they are their their parents waiting for class to start. DD has not problem talking to anyone ever!) the teacher asked me if we had said something to her. We had talked about it after that class and we how we wanted her to behave. The next two weeks we did talk about listening and doing what the teacher asked. The last week we probably talked for just a minute or two on the way to class. We were not reminding her or it all the time or anything. Well, DH just called and this is her 3rd week since we observed. She did not get a sticker this week at the end of class because she was not a good listener again. I do not know what to do. We tried talking to her about it and then this week I tried not talking to her about it, but just being positive and encouraging. She loves loves this class. She is learning so much, but I do not know how to help her. She loves it and I am afaid they are going to ask her to leave. I think part of the problem might be this is her only interaction with kids all week. She is home with either DH or grandparents all day. All the preschools around here would not take her till 3 and all but one (which we did not like) run Septepmber to June so putting her in January is not a option. Money is tight right now so maybe we need to sign her up for another class and we can swing it if needed but it would be tight but doable. What to do? I do not want to bribe her but, should we do something like if she does well she gets something? I am at a loss.

Re: Help- she will not stop talking (repost from BMB edited for clarity)
That totally crossed our minds. She had a good first month so the teacher felt really good about her staying. She was in swimming, art class, and library classes. She though aged out of the library classes. They only now have story time for 3-5 year olds ( since she was turning 3 during the next session she was not allowed to sign up again for the previous class type. We did those though from last year till just a few weeks ago. She is also not able to start the pre school story time till after she turns 3.) The art class was the same night as dance, and for the swim classes we were encouraged to not start again till after she was 3 because the class that was from 18-36 months was all younger kids and they felt she had aged out. We were looking for something else for her since she hads aged out of 2 of the three. We were looking for something because we felt we were just stuck in an in between age. We knew going in that she might not be fully ready but after the first month she was doing well according to the teacher so they measured her for a recital costume which we have paid for already. We were ready to pull her out if she was not ready, but everyone thought it was going ok.
We are no permitted to be in the room. We are in the waiting room. It is too cold right now to go outside for a long time. Although every day it is warm enough we do get her outside but we are in northern ohio. There are very few moms groups around here. I do not know any other stay at home dads. I will look though. DH is even comfortable with a moms group if they are ok with him.
