I just caught five minutes of Supernanny and by my current beliefs about child rearing it seems really outdated.
I agree with the key elements: boundaries, communication, eating together as a family, helping children understand what behaviour is unacceptable (or 'unasseptable' as Jo says).
But the naughty step? Forced apologies and forced hugs post punishment? That all just seem a bit weird to me. I think I found forcing a stroppy child to hug most jarring.
I know SN is called in when the children/family really need help, so we're not talking about 'normal' behaviour management requirements - but still...
Disclaimer - DD is five months old, I might be all about the naughty step in five years!
