Help, my dd is quite bright, devious, manipulative and does deliberately naughty things. She does not do it to get attention as she conceals her mis-deeds. It's like she's trying to get one over on you. She's only 3 and I've noticed the behaviour getting worse lately. I need a new dicipline structure that will work - naughty step doesn't work for us she just sits there happily and winds me up she says sorry and she isn't sorry. She goes there of her own accord. I'm trying behaviour charts atm. Is there a good book or disipline structure that can be recommended that isn't supernanny?
