Is it that she won't look when you call her name or that she just won't do what you tell her to do?
If she's not doing what she's told, then discipline. Whatever form you use. We use timeouts here....they stand in time out until they are ready to listen to me and do what they are told. Once out of timeout, if they don't do what I had told them to do, they go right back in.
Keep in mind that they know the difference between a statement and a question at this age....if you want her to do something, don't ASK her to do it.
There's a difference between "Will you put your toy away please?" and "Go put your toy away please." The former is a question which they can answer.....the latter is an "order".
