DD who is 4 just can't seem to tell the truth at the moment, she lies about everything and obvious lies, for example while she is eating breakfast she will say she hasn't had any breakfast today?!? she comes home from school telling lie after lie about what happened that day....for example her teacher wasn't there today when I know full well she was there all day etc etc How on earth do I stop this behaviour, I've lost count of the amount of times I have calming explained why telling lies is wrong but it has no impact on her
