I just wanted to share a book I've been reading that I really like, while I don't always totally agree with some of the things they say and I think they sometime go a little overboard in getting their ideas across, I think the ideas and basis of it are great. It is written by Christian authors but is not overly religious (in fact, hardly at all).
It's called "Parenting with Love and Logic". It's about raising responsible children. They are for gentle discipline and actually say to let natural consequences teach your children unless they are in danger or the consequence will affect the rest of their life. The younger your child, the "less expensive" the natural consequence is usually. And by the time they are older, they have learned to make good decisions because of dealing with the natural consequences of decisions they have made in the past.
It is also about showing unconditional love so your child knows they are loved even if they made a bad decision. And about giving some control to the child by offering choices.
I am sure I am not doing this justice....here is their website...
