I'm unsure of what to do with my daughter these days. She's 5 1/2, and the last few weeks has been quite different- speaking with tonnes of attitude to me and her dad, stomping her foot if she's upset or told no to something, not listening, and then today, kicked my leg and pushed my stomach and thought it was funny and wouldn't stop laughing. Talking with her about how she treats others hasn't resulted in any change in her behavior, and sending her to her room to cool off, then call me when she's ready doesn't work either. I'm unsure of what to do to get through to her, and get a much needed change in her attitude. Any ideas?
