She can be a lovely child at times but over the past 18 months has started to use a tone of voice which I consider disrespectful and at times downright rude. I pick her up on it every time and have sent her to her room, got angry, told her off in public (which she doesn't like but which I am prepared to do).
It doesn't seem to improve. She is not always like this, especially when she wants something (lol!) but it's getting me down and I wonder if anyone else has used strategies that have worked? I really really don't want her to enter teenagerdom speaking like this or else we are going to clash terribly
