The only specific source I can give you at the moment (though I will do some more research later today) is the bible. There is a lot on relationships in there. Not only will you find some good information, if you believe in God it can also help you experience peace. If you're not terribly familiar with finding things in the bible, you may want to use a concordance or a study bible (I'm partial to McArthurs, but that's just me).
Other than that, you may want to check out psychology books, parenting magazines, and another great source: your pediatrician. They can point you to all kinds of resources. Also, check with the social worker at your local hospital. They want to help (at least, they do at the hospital I work at) and can often provide a plethora of resources. To that end, I'll check with the weekend social worker and see what she says.
My belief on this (and yes, it is biblically based) is that children tend to imitate and search out what they've seen in their family. Where did I find that? "the sins of the father will carry into the third and fourth generations..." From a psychological standpoint, people learn by watching other people interact. Your children will do one of two things from it: they will either end up acting similarly to what the two of you do, or they will rebel and go to the far opposite. You know what I mean: a mother who is obsessively neat ends up with a daugher who is very disorganized. A father with anger management problems ends up with a son who never raises his voice. Or, you can end up with something like this: a very "loose" mother who gets pregnant as a teen, ends up with a daugher who also gets pregnant as a teen and sleeps around, who then ends up with a daughter who also gets pregnant at the same age.
I don't know if that makes any sense, but I wanted to respond to your post because I've been thinking about that a lot myself lately.
