DD is 2.5yrs and v cheeky. If she is told not to do something she just ignores us and doesnt seem to care if she is punished. Have tried naughty chair, no tv etc. She often wont eat her dinner and has to go to bed with nothing but it doesnt seem to make any difference. We ask her to say sorry if she is naughty or hurts someone which she will sometimes do but I dont think she really understands as she will just go and do it again. She shouts 'dont tell me not to do it!!!' or 'no!!' when asked to do something. Am I expecting too much from her? Its her cheekiness which upsets me most as I cant think where she has learnt to speak to us in that way!!
