No advice, just wanted to note that child lying is so visceral for me. I logically know that there is magical thinking, punishment avoidance, etc, etc. But it so disconcerting - - in particular when they lie well!! I start imagining future wall street fraud, cheating on their SATs etc and I feel my blood pressure rising. It feels like a slap in the face to my top priority for my kids' development. It is an emotional issue for many adults, especially when they have emphasized values education. Even though we know rationally it is a normal part of childhood.
