Ds(6) has started lying everyday. It's fairly harmless stuff but pretty high volume. Often it's "I got a well-done sticker at school" type things. I have been responding with a "oh darling, I will thank your teacher tomorrow" at which point he backtracks. If this strategy fails should I follow through or would that really be unreasonably mean?
Am I just being OTT? I know all kids experiment with lies but it's got to a point where we have run out of ideas. He knows it's wrong and why. We did the whole book about it thing, consequences etc.
Ideas?
